continued cooperation and Turkey’s membership in the North Atlantic Treaty Organization

(NATO). Observers voice concerns about the largely authoritarian rule of Turkish President
Recep Tayyip Erdogan. Major inflation and a sharp decline in Turkey’s currency have led to

speculation that Erdogan and his Justice and Development Party (Turkish acronym AKP) might
be vulnerable to a coalition of opposition parties in presidential and parliamentary elections scheduled for May 14, 2023. The
aftermath of the disastrous February 6, 2023 earthquakes in southern Turkey is affecting Turkey’s politics, society, and
economy, and could influence election outcomes. If opposition candidate Kemal Kilicdaroglu were to win 2023 elections and
take power, or if Erdogan were to win reelection but lose control of parliament, some domestic and foreign policy changes
could be possible.
U.S. relations and F-16s. Under President Joe Biden, existing U.S.-Turkey tensions have continued alongside cooperation
on other foreign policy matters. While deepening ties with Russia remain a cause for U.S. concern, Turkey’s emergence as a
mediator between Russia and Ukraine after Russia’s 2022 invasion has arguably increased Turkey’s importance for U.S.
policy. U.S.-Turkey relations have improved somewhat due to Turkey’s support for Ukraine’s defense; growing relationships
with other countries that seek to counter Russian regional power (including via the export of drone aircraft); and openness to
rapprochement with Israel, some Arab states, and Armenia. President Biden has voiced support for sales that would upgrade
Turkey’s aging F-16 fleet, but some Members of Congress have expressed opposition. The Administration reportedly
provided informal notification to Congress in January 2023 of possible sales of F-16s to Turkey, plus associated equipment
and munitions. Factors potentially influencing congressional deliberations include Turkey’s potential agreement to NATO
accession for both Sweden and Finland, and Turkey’s tense relations with Greece. Congressional and executive branch action
regarding Turkey and its neighboring countries could have implications for bilateral ties and U.S. political-military options in
the region, as well as Turkey’s strategic orientation. The following are key factors in the U.S.-Turkey relationship.
Turkey’s foreign policy approach. For decades, Turkey has relied closely on the United States and NATO for defense
cooperation. Turkish leaders have indicated an interest in reducing their dependence on the West, and that may partly explain
their willingness to coordinate some actions with Russia. Nevertheless, Turkey retains significant differences with Russia in
Syria, Ukraine, Libya, and Armenia-Azerbaijan. Turkey’s future foreign policy course could depend partly on how willing
Turkey is to risk tensions or breaks in traditional relationships with Western powers while building other global relationships.
Major issues: Russia, Sweden-Finland-NATO, and Greece. In the wake of Russia’s 2022 invasion of Ukraine, Turkey
faces challenges in balancing its relations with the two countries and managing Black Sea access, with implications for U.S.-
Turkey ties. To some extent, Erdogan has sought to reinforce Turkey’s embattled economy by deepening economic and
energy ties with Russia. Erdogan might assess that Western sanctions against Russia give Turkey increased leverage in these
dealings. At the same time, Turkey has expanded defense cooperation with Ukraine. Turkey has become an important
mediator between Russia and Ukraine on brokering a grain export corridor and other issues. Turkey appears poised to
approve Finland’s NATO membership by April 2023, while conditioning final approval for Sweden on action against people
that Turkey considers to be terrorists. Long-standing disputes between Greece and Turkey over territorial rights in the
Aegean and Eastern Mediterranean seas spiked in 2022 amid greater U.S. strategic cooperation with Greece, but tensions
have somewhat subsided in early 2023 after Greece provided some post-earthquake relief assistance to Turkey.
Syria: ongoing conflict near borders. Turkish concerns regarding its southern border with Syria have deepened further
during Syria’s civil war, due largely to (1) the flow of nearly four million refugees into Turkey, (2) U.S. efforts to counter the
Islamic State by working with Syrian Kurds linked to the Kurdistan Workers’ Party (Kurdish acronym PKK, a U.S.-
designated terrorist organization), and (3) the presence of Russian, American, and Iranian forces in Syria that complicate and
somewhat constrain Turkish action. Turkey and allied Syrian armed opposition groups have occupied various areas of
northern Syria since 2016, and Turkey’s military continues to target Kurdish fighters in Syria and Iraq.

Introduction and Key U.S.-Turkey Considerations
This report provides background information and analysis on key issues affecting U.S.-Turkey
(Türkiye)1 relations, including domestic Turkish developments and various foreign policy and
defense matters. Turkey has been a member of the North Atlantic Treaty Organization (NATO)
since 1952. U.S. and Turkish officials maintain that cooperation on regional security matters
remains mutually important,2 despite Turkey’s 2019 acquisition of an S-400 surface-to-air
defense system from Russia and a number of other U.S.-Turkey differences (such as in Syria and
with Greece and Cyprus).
Under President Joe Biden, some existing U.S.-Turkey tensions have continued alongside
cooperation on other matters and opportunities to improve bilateral ties. While continued or
deepening ties with Russia in certain areas remain a cause for concern for the Biden
Administration and some Members of Congress, Turkey’s support for Ukraine’s defense and
openness to rapprochement with Israel, some Arab states, and Armenia have somewhat improved
U.S.-Turkey relations.3 President Biden has expressed support for selling F-16s to Turkey, and in
January 2023 the Administration reportedly informally notified Congress of a potential F-16 sale,
plus associated equipment and munitions (see “Possible F-16 Sales and Congressional Views”
below).
Members of Congress may consider legislative and oversight options regarding Turkey.
Congressional and executive branch action regarding Turkey and its rivals could have
implications for bilateral ties, U.S. political-military options in the region, and Turkey’s foreign
policy orientation and financial well-being.

Domestic Issues
Political Developments Under Erdogan’s Rule
President Recep Tayyip Erdogan (pronounced air-doe-wan) has ruled Turkey since becoming
prime minister in 2003, and has steadily deepened his control over the country’s populace and
institutions. After Erdogan became president in August 2014 via Turkey’s first-ever popular

1 In late 2021, President Erdogan directed the use of “Türkiye” (the country’s name in Turkish) in place of “Turkey” or
other equivalents (e.g., the German “Türkei,” the French “Turquie”) in Turkish government documents and
communications. In June 2022, the United Nations accepted the Turkish request to change the country’s name at the
body to “Türkiye.” In January 2023, the State Department spokesperson said that the department would use the revised
spelling “in most formal diplomatic and bilateral contexts” where appropriate. The U.S. Board on Geographic Names
retained both “Turkey” and “Republic of Turkey” as conventional names, and the spokesperson said that the State
Department could use those names if it is in furtherance of broader public understanding. State Department Press

presidential election, he claimed a mandate for increasing his power and pursuing a presidential
system of governance, which he cemented in a 2017 referendum and 2018 presidential and
parliamentary elections. Some allegations of voter fraud and manipulation surfaced after the
referendum and the elections.4 Since a failed July 2016 coup attempt by elements within the
military, Erdogan and his Islamist-leaning Justice and Development Party (Turkish acronym
AKP) have adopted more nationalistic domestic and foreign policy approaches, perhaps partly
because of their reliance on parliamentary support from the Nationalist Action Party (Turkish
acronym MHP).
Many observers describe Erdogan as a polarizing figure, and elections have reflected roughly
equal portions of the country supporting and opposing his rule.5 The AKP won the largest share of
votes in 2019 local elections, but lost some key municipalities, including Istanbul, to candidates
from the secular-leaning Republican People’s Party (Turkish acronym CHP).
U.S. and European Union (EU) officials have expressed a number of concerns about authoritarian
governance and erosion of rule of law and civil liberties in Turkey.6 Some leading opposition
figures in Turkey have accused Erdogan of planning, controlling, and/or using the failed coup to
suppress dissent and consolidate power.7
Meanwhile, Turkish authorities have continued their on-and-off efforts to counter militants from
the Kurdistan Workers’ Party (Kurdish acronym PKK, a U.S.-designated terrorist organization).
These efforts include Turkish military operations targeting PKK and PKK-aligned personnel in
Iraq and Syria.8
February Earthquakes and Their Implications
Two major earthquakes (magnitude 7.8 and 7.5) hit southern Turkey on February 6, 2023. Quake
damage and its after-effects in areas of Turkey and Syria have reportedly killed more than 48,000
people in Turkey and 6,000 in Syria, injured over 100,000 more, and directly affected the living
situations and daily lives of millions. According to an assessment prepared by Turkey’s Strategy
and Budget Office with the assistance of various international organizations, as of March 2023
3.3 million people in Turkey had been displaced, and nearly two million are being sheltered in
tent or container camps.9 As Turkish authorities coordinate a humanitarian response involving
significant international assistance, and facilitate access to Syrian border crossings, observers
have sought to assess (1) factors contributing to the damage and its scope, (2) efforts to help
victims and their families, and (3) present and future needs.10 U.S. officials have provided or

announced various means of assistance to Turkey, including $235 million in urgent humanitarian
assistance.11 With Turkey’s government estimating the economic toll from the earthquakes to be
around $104 billion—roughly 9% of Turkey’s annual gross domestic product (GDP)—
international pledges of assistance to date total nearly $7.5 billion.12
The crisis is affecting Turkey’s politics, society, and economy, particularly as the country
prepares for presidential and parliamentary elections (discussed below). Parliament approved a
three-month state of emergency (scheduled to end in early May) in the ten southern Turkish
provinces most directly affected. These provinces account for about 10% of Turkey’s gross
domestic product and 15% of its population, and host thousands of refugees from Syria’s ongoing
civil war.13
Analysts speculate about how the crisis will affect support for President Erdogan and his
government.14 A major 1999 earthquake in northwestern Turkey killed approximately 18,000,
prompting legal and regulatory efforts to improve building safety.15 However, some media
accounts and opposition politicians allege that in the years before the 2023 earthquakes,
government officials and contractors prioritized economic benefits over adherence to construction
codes, at least partly contributing to the scope of damage and fatalities.16 Erdogan has denounced
criticism aimed at him or the government as fomenting disunity,17 and Turkey’s justice ministry
has ordered prosecutors to create “earthquake crimes investigation units” to consider criminal
violations for substandard work.18 Erdogan acknowledged some problems with the government’s
initial response,19 while mainly attributing the disaster to the quakes’ size.20 He has announced a
government-led recovery program, pledging to build 319,000 houses within a year, and 650,000
in total. Some local officials, engineers, and international donors have expressed concern that a
quick rebuilding effort without detailed planning or clearer accountability measures could leave
the new buildings vulnerable to future seismic activity.21

Major Economic Challenges
Ongoing economic problems in Turkey considerably worsened in 2022 as its currency, the lira,
depreciated in value around 28% against the U.S. dollar, after declining by nearly 45% in 2021.
After reaching a 24-year-peak of 86% in October 2022, official annual inflation was at 55% in
February 2023.22 Many analysts link the spike in inflation to the Turkish central bank’s repeated
reductions of its key interest rate since September 2021, with additional inflationary pressure
possibly coming from external events such as Russia’s war on Ukraine and interest rate hikes in
the United States and other major economies.23 The lira has been trending downward for more
than a decade, with its decline probably driven in part by broader concerns about Turkey’s rule of
law and economy.24
Throughout this time, President Erdogan has assertively challenged the conventional economic
theory that higher interest rates stem inflation, attract foreign capital, and support the value of the
currency. In replacing Turkey’s central bank governor and finance minister in 2021, Erdogan
established greater control over Turkish fiscal and monetary policy. In public statements, Erdogan
has argued that lower interest rates boost production, employment, and exports.25 Erdogan also
has criticized high interest rates as contrary to Islamic teachings and as exacerbating the gap
between rich and poor.26
The currency and inflation crisis in Turkey has dramatically affected consumers’ cost of living
and the cost of international borrowing (mostly conducted in U.S. dollars) for banks and private
sector companies. The government has sought to stop or reverse inflation by providing tax cuts,
minimum wage increases, greater access to early retirement benefits, and subsidies for basic
expenses, along with borrowing incentives for banks that hold liras.27 Turkey also has sought
currency swaps from some Arab Gulf states, and has benefitted from Russian-origin inflows that
contribute to U.S. warnings about potential sanctions evasion (see “Turkey-Russia Economic and
Energy Cooperation”
below).28
Costs of ongoing humanitarian assistance and reconstruction from the earthquake crisis, along
with disruptions to agricultural, industrial, and commercial activity, will likely strain Turkey’s
economy further.29 With the overall cost estimated to approach $104 billion, the Economist
Intelligence Unit predicts a 0.3% drop in economic growth and 1.4% increase in the budget
deficit-to-GDP ratio for 2023.30 Turkey’s modest debt-to-GDP ratio of around 37% (see Figure

A-1) may permit it some space to boost fiscal spending in response to the crisis. One analyst has
said that financial assistance from international development banks will be necessary but limited
because of the Turkish government’s poor relations with the West.31
2023 Elections
Turkey’s next presidential and parliamentary elections are required under Turkey’s constitution to
take place by June 18, 2023. In March, President Erdogan scheduled the elections to occur on
May 14. Questions persist regarding how to overcome logistical challenges to voting that the
millions of persons displaced by the February earthquakes might face.
Largely in the context of Turkey’s economic problems discussed above, public opinion polls have
fueled speculation that Erdogan and the AKP-MHP parliamentary coalition might be vulnerable
to a coalition of six opposition parties led by the CHP and the Good (Iyi) Party (see Appendix B
for profiles of selected party leaders).32 Some observers have debated whether (1) free and fair
elections could take place under Erdogan,33 (2) opposition parties can convince potential swing
voters to side with them despite their personal or ideological affinity for Erdogan,34 or (3)
Erdogan would cede power after an electoral defeat.35 If no presidential candidate receives more
than 50% of the vote, a presidential run-off election between the top two vote-getting candidates
would take place two weeks later, on May 28.
The opposition coalition has agreed on a joint platform focused on returning Turkey to the
parliamentary system that existed before the 2018 election, largely as a means of limiting
executive power.36 Opposition figures also have criticized the Erdogan government’s approach to
a range of foreign and domestic policy issues and promised to make changes (see also “Foreign
Policy Changes Under a Different President?”)
.37 In its platform, the opposition has hinted at
more orthodox economic policies, saying that it would reduce inflation and impose no
responsibilities on the Central Bank other than ensuring price and financial stability.38
In March 2023, the opposition nominated CHP party leader Kemal Kilicdaroglu (kuhl-utch-dahr-
oh-loo
) as its joint candidate.39 Kilicdaroglu’s most important coalition partner, Good Party leader
Meral Aksener (awk-sheh-nar), eventually agreed to support Kilicdaroglu after two other
potential candidates who had polled more favorably against Erdogan—Istanbul mayor Ekrem
Imamoglu and Ankara mayor Mansur Yavas—backed Kilicdaroglu in response to Aksener’s last-

ditch appeal for one of them to run. Imamoglu’s prospects may have been undermined by a
criminal conviction (pending final resolution on appeal) that he and other opposition figures
charge is politically motivated.40
How Kurdish citizens of Turkey (numbering nearly 20% of the population) vote could impact the
outcome. Kilicdaroglu has sought to enlist Kurdish support for his bid to unseat Erdogan “without
antagonizing nationalist voters in the diverse opposition bloc that nominated him.”41 While
Aksener’s Good Party rejects a formal alliance between the opposition and the Kurdish-led
Peoples’ Democratic Party (Turkish acronym HDP), the HDP’s decision in March to drop plans
to field a presidential candidate could assist Kilicdaroglu’s prospects in building an anti-Erdogan
majority.42 The HDP also has arranged to run in parliamentary elections under the aegis of the
Green Left Party to prevent against its exclusion, because a case pending before the
Constitutional Court could ban the HDP from campaigning under its own name.43
Some initial polling has suggested that voters may favor Kilicdaroglu over Erdogan by more than
a 10% margin, and that the opposition also could prevent Erdogan’s AKP-MHP coalition from
retaining its parliamentary majority.44 Despite Erdogan’s potential vulnerability, some observers
have questioned the opposition coalition’s prospects, citing obstacles posed by disunity,
Erdogan’s political resilience, and the government’s influence over the media, economic
developments, and judicial rulings.45 It is unclear how voters will respond to the earthquake
crisis.46 An AKP official claimed in March that internal polling showed Erdogan and the AKP-
MHP coalition ahead in a close race.47 The Economist Intelligence Unit has said that Erdogan
could win the presidential election but lose his parliamentary majority, while also assessing that a
close contest could lead to “divisive court challenges” and “political instability.”48
If the president’s party coalition does not control parliament after the elections, parliament could
check the president in various ways if a majority of members seeks to do so. The president has
broad powers to appoint cabinet ministers and act in the absence of parliamentary initiative, but
relies on parliament’s approval in certain matters such as budgeting, international treaty
ratification, and foreign military deployments.49

Turkey (Türkiye): Major Issues and U.S. Relations

Turkish Foreign Policy
General Assessment
Turkey’s strategic orientation, or how it relates to and balances between the West and other global
and regional powers, is a major consideration for the United States. Trends in Turkey’s relations
with the United States and other countries reflect changes to this orientation, as Turkey has sought
greater independence of action as a regional power within a more multipolar global system.
Turkish leaders’ interest in reducing their dependence on the West for defense and discouraging
Western influence over their domestic politics may partly explain their willingness to coordinate
some actions with Russia, such as in Syria and with Turkey’s purchase of a Russian S-400
surface-to-air defense system. Nevertheless, Turkey retains significant differences with Russia—
with which it has a long history of discord—including in political and military crises involving
Syria, Ukraine, Libya, and Armenia-Azerbaijan.
Turkish leaders appear to compartmentalize their partnerships and rivalries with other influential
countries as each situation dictates, partly in an attempt to reduce Turkey’s dependence on these
actors and maintain its leverage with them.50 Turkey’s future foreign policy course could depend
partly on the degree to which Turkish leaders feel constrained by their traditional security and
economic relationships with Western powers, and how willing they are to risk tensions or breaks
in those relationships while building other global relationships.
Foreign Policy Changes Under a Different President?
In anticipation of 2023 elections, observers have speculated about how a new president’s foreign
policy (including domestic policy with clear foreign policy ramifications) might differ from
Erdogan’s if an opposition candidate wins.51 Because of widespread nationalistic sentiment
among Turkey’s population and most of its political parties, a different president may have
difficulty changing Turkish policies on some of the following matters of core security concern:
Syria and Iraq (Kurdish militancy, refugee issues, and other countries’ influence), Greece and
Cyprus (Aegean and Eastern Mediterranean disputes), and Russia and Ukraine (conflict and its
regional and global consequences).
However, a different president may be more likely to alter certain ongoing policies that may be
more reflective of Erdogan’s or the AKP’s preferences than of broad national consensus. Such
changes may include (1) providing more flexibility to central bankers and other officials on
monetary policy decisions and other measures to address Turkey’s economic problems, (2) giving
greater consideration to European Court of Human Rights rulings, and (3) reducing Turkish
support for Sunni Islamist groups like Hamas (a U.S.-designated terrorist organization), the
Egyptian Muslim Brotherhood, and Syrian armed opposition factions.
Some Turkish opposition parties’ foreign policy statements suggest that a different president
might be less willing than Erdogan to say and do things that risk harming relationships with the
United States and European countries.52 Thus, despite the difficulties that may surround changing

some policies (as mentioned above), a different Turkish president could conceivably be less
inclined toward implementing those policies in a way that might worsen relations with Western
states, such as by pursuing additional arms purchases from Russia or new military operations in
northern Syria or the Aegean/Eastern Mediterranean area. However, if a new, untested Turkish
government feels pressure to signal its strength to various international actors or to placate
multiple domestic constituencies within a coalition, that president may strive to match Erdogan’s
reputation for assertiveness. Conversely, a president facing lack of consensus within a coalition
might become more passive on foreign policy.
U.S./NATO Strategic Relationship and Military Presence
The United States has valued Turkey’s geopolitical importance to and military strength within the
NATO alliance, while viewing Turkey’s NATO membership as helping anchor Turkey to the
West. The State Department’s Integrated Country Strategy (ICS) for Turkey says that its sizable
military (the second-largest in NATO) and its geographic location at the southeastern flank of the
alliance gives it a critical role in regional security.53 Turkey’s proximity to several conflict areas
in the Middle East and elsewhere has made the continuing availability of its territory for the
stationing and transport of arms, cargo, and personnel valuable for the United States and NATO.
In addition to Incirlik Air Base near the southern Turkish city of Adana, other key U.S./NATO
sites include an early warning missile defense radar in eastern Turkey and a NATO ground forces
command in Izmir (see Figure A-2). Turkey also controls access to and from the Black Sea
through the Bosphorus (alt. Bosporus) and Dardanelles Straits (the Straits—see Figure A-3).
For Turkey, NATO’s traditional importance has been to mitigate Turkish concerns about
encroachment by neighbors, such as the Soviet Union’s aggressive post-World War II posturing
leading up to the Cold War. Additionally, NATO security guarantees compensate Turkey for a
general lack of nationally owned strategic defense and deterrence capabilities.54 In more recent or
ongoing arenas of conflict like Ukraine and Syria, Turkey’s possible interest in countering
Russian objectives may be partly motivating its military operations and arms exports.55
Tensions between Turkey and other NATO members have fueled internal U.S./NATO discussions
about the continued use of Turkish bases. Some reports suggest that expanded or potentially
expanded U.S. military presences in places such as Greece, Cyprus, and Jordan might be
connected with concerns about Turkey.56 In March 2022 congressional hearing testimony, Turkey
expert and former congressional committee staff member Alan Makovsky said that while the
United States should make efforts to keep Turkey in the “Western camp,” Turkish “equivocation
in recent years” justifies the United States building and expanding military facilities in Bulgaria,
Romania, and Greece to “hedge its bets.”57

Turkey (Türkiye): Major Issues and U.S. Relations

Russia
Turkey’s relations with Russia feature elements of cooperation and competition. Turkey has made
a number of foreign policy moves since 2016 toward closer ties with Russia. These moves could
be motivated by a combination of factors, including Turkey’s effort to reduce dependence on the
West, economic opportunism, and chances to increase its regional influence at Russia’s expense.
Turkey also has moved closer to a number of countries surrounding Russia—including Ukraine
and Poland—likely in part as a counterweight to Russian regional power.58
Russia’s 2022 Invasion of Ukraine and Turkish Mediation Efforts
Russia’s 2022 invasion of Ukraine has heightened challenges Turkey faces in balancing its
relations with the two countries, with implications for U.S.-Turkey ties. Turkey’s links with
Russia—especially its 2019 acquisition of a Russian S-400 system—have fueled major U.S.-
Turkey tensions, triggering sanctions and reported congressional holds on arms sales (discussed
below). However, following the renewed Russian invasion of Ukraine, U.S. and Turkish interests
in countering Russian revisionist aims—including along the Black Sea coast—appear to have
converged in some ways as Turkey has helped strengthen Ukraine’s defense capabilities in
parallel with other NATO countries.59 In addition to denouncing Russia’s invasion, closing the
Straits to belligerent warships, opposing Russian claims to Ukrainian territory (including
Crimea), and serving as a transit hub for natural gas to Europe,60 Turkey has supplied Ukraine
with various types of military equipment—including armed drone aircraft and mine-resistant
ambush-resistant (MRAP) vehicles61—as well as humanitarian assistance. Nevertheless, Turkey’s
leaders likely hope to minimize spillover effects to Turkey’s national security and economy, and
this might partly explain Turkey’s continued engagement with Russia and desires to help mediate
the conflict (discussed below).
In January 2023, a media outlet reported that Turkey began transferring some dual-purpose
improved conventional munitions (or DPICMs, which are artillery-fired cluster munitions) to
Ukraine in November 2022. The report cited various observers debating the potential battlefield
impact and humanitarian implications of the weapon’s use.62 Turkish and Ukrainian officials have
denied that any such transfers have occurred.63

Turkey (Türkiye): Major Issues and U.S. Relations

Turkey and Ukraine have strengthened their relations since Russia’s invasion of Crimea in 2014.64 In 2017, a
Turkish security analyst attributed these closer ties to growing mutual interests in countering Russian influence in
the Black Sea region and in sharing military technology to expand and increase the self-sufficiency of their
respective defense industries.65 Since 2020, the two countries have signed multiple agreements signifying closer
cooperation, and also signed a broader free trade agreement (pending ratification) in February 2022.66
In line with these agreements, Turkish and Ukrainian companies have engaged in or planned a significant expansion
of defense transactions, including a number of joint development or co-production initiatives.67 Turkish expertise
with drone and other aircraft and naval platforms complements Ukrainian skil s in designing and constructing
aerospace engines and missiles.68 As part of the deepening bilateral defense cooperation, Turkey has sold several
Turkish-origin Bayraktar TB2 drones to Ukraine since 2019,69 and some reports have suggested that the
manufacturer has delivered additional TB2s to Ukraine at various times since Russia’s 2022 invasion.70 Additionally,
Turkey is helping establish Ukraine’s naval capabilities by producing corvettes (small warships) for export.71
Turkey’s maintenance of close relations with both Russia and Ukraine, and its ability to regulate
access to the Straits has put it in a position to mediate between the parties on various issues of
contention. In July 2022, Turkey and the United Nations entered into parallel agreements with
Russia and Ukraine to provide a Black Sea corridor for Ukrainian grain exports that could partly
alleviate global supply concerns.72 Under the deal, which currently runs until May 2023, Turkey,
Russia, Ukraine, and the U.N. have representatives at a joint coordination center in Istanbul to
oversee implementation and inspect ships to prevent weapons smuggling.73 President Biden has
expressed appreciation for Turkey’s efforts.74
Turkey-Russia Economic and Energy Cooperation
Turkish officials have sought to minimize any negative economic impact Turkey might face from
the Russia-Ukraine war, partly through boosting various forms of economic and energy
cooperation with Russia. These efforts may stem from Turkish leaders’ concerns about improving

the country’s economic profile in advance of 2023 elections.75 The Turkish government has not
joined economic sanctions against Russia or closed its airspace to Russian civilian flights.
In August 2022, Presidents Erdogan and Putin publicly agreed to bolster Turkey-Russia
cooperation across economic sectors.76 Turkey’s Russia-related dealings could potentially lead to
Western secondary sanctions against Turkey for facilitating Russian sanctions evasion. During a
February 2023 trip to Turkey and the United Arab Emirates to emphasize U.S. concerns about the
dangers of “dark money flowing through their financial systems,” Brian Nelson, Under Secretary
of the Treasury for Terrorism and Financial Intelligence, delivered the following remarks to
leaders of Turkish financial institutions:
We of course recognize Türkiye’s reliance on Russian energy imports and trade in
agricultural goods, and continue to work to mitigate adverse impacts to these economic
activities.
However, the marked rise over the past year in non-essential Turkish exports or re-exports
to Russia makes the Turkish private sector particularly vulnerable to reputational and
sanctions risks. This is being driven by Moscow....
In engaging with sanctioned Russian entities, Turkish businesses and banks could put
themselves at risk of sanctions and a potential loss of access to G7 markets and
correspondent relationships.
Turkish businesses and banks should also take extra precaution to avoid transactions
related to potential dual-use technology transfers that could be used by the Russian
military-industrial complex.77
Some Turkish banks and companies appear to be limiting or considering limits on certain types of
transactions and services with Russian businesses.78 Turkish Foreign Minister Mevlut Cavusoglu
has denied that Turkish businesses are exporting electronic or technological products with
potential defense applications to Russia, but has publicly welcomed information sharing with
U.S. and EU counterparts to ensure that businesses do not use Turkey to bypass Western
sanctions.79 Reportedly, Turkey began in March 2023 to enforce curbs on sanctioned goods
transiting its territory to Russia.80
NATO Accession Process for Sweden and Finland
Sweden and Finland formally applied to join NATO in May 2022, following Russia’s invasion of
Ukraine. Turkey objected to the formal start of the two countries’ accession process, delaying it

for more than a month. Under Article 10 of the North Atlantic Treaty, the admission of new allies
requires the unanimous agreement of existing members (Figure A-4).
The Turkish objections centered around claims that Sweden and Finland have supported or
harbored sympathies for groups that Turkey’s government deems to be terrorist organizations,
namely the Fethullah Gulen movement81 (which the government has blamed for involvement in
the 2016 failed coup) and the PKK.82 (The United States and EU also classify the PKK as a
terrorist group, but not the Gulen movement.) Turkey demanded that Sweden and Finland lift the
suspension of arms sales they had maintained against Turkey since its 2019 incursion into Syria
against the PKK-linked Kurdish group (the People’s Protection Units—Kurdish acronym YPG)
that has partnered with the U.S.-led anti-Islamic State coalition.83 Turkey removed its objections
to starting the accession process after NATO Secretary General Jens Stoltenberg mediated a June
2022 memorandum between Turkey, Sweden, and Finland. In the trilateral memorandum, the
three countries confirmed that no arms embargoes remain in place between them. Further,
Sweden and Finland agreed not to support the YPG or Gulen movement, and pledged to work
against the PKK.84
Since then, Turkey has continued to press Sweden and Finland to extradite people that Turkey
considers to be terrorists. Under the June 2022 trilateral memorandum, Sweden and Finland
agreed to address Turkey’s pending deportation or extradition requests in various ways, but did
not commit to specific outcomes in those cases.85 Sweden’s prime minister and other sources
have indicated that neither Sweden nor Finland are inclined to make political decisions on
extradition that contravene domestic judicial findings conducted under due process and the rule of
law.86 In January 2023, Turkish presidential adviser Ibrahim Kalin said that Turkey would only be
in a position to agree to Sweden’s accession after it passed new anti-terror laws, a process he
estimated would take about six months.87 Erdogan then called on Sweden and Finland to extradite
“around 130” people.88
In January 2023, the Wall Street Journal cited unnamed U.S. officials predicting that
congressional approval of a possible F-16 sale to Turkey (see “Congressional Notification
Process”
below) would be tied to Turkish approval of Sweden’s and Finland’s NATO accession.89

have indicated that they may only consider supporting an F-16 sale to Turkey if accession moves
forward for both Sweden and Finland.90 In March, Erdogan hosted Finnish President Sauli
Niinisto in Turkey and expressed his support for Finland’s accession.
While Turkey’s parliament appears poised to ratify accession protocols for Finland by April
2023,91 it might not address Sweden’s case before the closely contested Turkish presidential and
parliamentary elections scheduled for May.92 Sweden’s government hopes that its proposed anti-
terror legislation will be approved by its parliament in time for it to take effect in early June.93 It
is unclear (1) whether and when Turkish ratification might proceed after that, (2) if Turkey’s
leadership after its elections might demand further Swedish actions, and (3) how a potential
future Turkish parliament that is not controlled by the president’s party coalition might act.94
NATO Secretary General Stoltenberg has said that he aims to have both Sweden and Finland join
NATO by the time of the alliance’s July 11-12 summit in Lithuania.95
Syria96
Turkey’s involvement in Syria’s conflict since it started in 2011 has been complicated and costly
and has severely strained U.S.-Turkey ties.97 Turkey’s priorities in Syria’s civil war have evolved
during the course of the conflict. While Turkey still opposes Syrian President Bashar al Asad, it
has engaged in a mix of coordination and competition with Russia and Iran (which support Asad)
since intervening militarily in Syria starting in August 2016. Turkey and the United States have
engaged in similarly inconsistent interactions in northern Syria east of the Euphrates River, where
U.S. forces have been based.
Since at least 2014, Turkey has actively sought to thwart the Syrian Kurdish YPG from
establishing an autonomous area along Syria’s northern border with Turkey. Turkey’s government
considers the YPG and its political counterpart, the Democratic Union Party (PYD), to be a major
threat to Turkish security, based on Turkish concerns that YPG/PYD gains have emboldened the
PKK (which has links to the YPG/PYD) in its domestic conflict with Turkish authorities.98 The
YPG/PYD has a leading role within the Syrian Democratic Forces (SDF), an umbrella group
including Arabs and other non-Kurdish elements that became the main U.S. ground force partner

against the Islamic State in 2015. Turkish-led military operations in October 2019 to seize areas
of northeastern Syria from the SDF—after U.S. Special Forces pulled back from the border
area—led to major criticism of and proposed action against Turkey in Congress.99 Turkey has set
up local councils in areas of northern Syria that Turkey and Turkish-supported Syrian armed
opposition groups—generally referred to under the moniker of the Syrian National Army
(SNA)—have occupied since 2016 (see Figure A-5).
Erdogan has hinted at the possibility of repairing relations with Asad, after more than a decade in
which Turkey has sought an end to Asad’s rule. As of early 2023, Russia is reportedly trying to
broker better ties.100 Turkey is seeking Syria’s help to push YPG fighters farther from the border
and facilitate the return of Syrian refugees living in Turkey. Asad reportedly wants full Turkish
withdrawal in return.101 It is unclear whether the two leaders can compromise and how that would
affect Turkey’s relationship with the SNA and the overall dynamic with other stakeholders in
northern Syria. In response to a question about potential Turkey-Syria rapprochement, the State
Department spokesperson has said that U.S. officials have told allies that now is not the time to
normalize or upgrade relations with the Asad regime.102
U.S.-Turkey Arms Sales Issues
How Turkey procures key weapons systems is relevant to U.S. policy in part because it affects
Turkey’s partnerships with major powers and the country’s role within NATO. For decades,
Turkey has relied on certain U.S.-origin equipment such as aircraft, helicopters, missiles, and
other munitions to maintain military strength.103
Russian S-400 Acquisition: Removal from F-35 Program,
U.S. Sanctions, and Congressional Holds
Turkey’s acquisition of the Russian S-400 system, which Turkey ordered in 2017 and Russia
delivered in 2019,104 has significant implications for Turkey’s relations with Russia, the United
States, and other NATO countries. As a direct result of the transaction, the Trump Administration
removed Turkey from the F-35 Joint Strike Fighter program in July 2019, and imposed sanctions
under the Countering America’s Adversaries Through Sanctions Act (CAATSA, P.L. 115-44) on
Turkey’s defense procurement agency in December 2020.105 In explaining the U.S. decision to
remove Turkey from the F-35 program in 2019, the Defense Department rejected the idea of
Turkey fielding a Russian intelligence collection platform (housed within the S-400) that could

detect the stealth capabilities of F-35s in Turkey.106 Additionally, Section 1245 of the FY2020
National Defense Authorization Act (NDAA, P.L. 116-92) prohibits the transfer of F-35s to
Turkey unless the Secretaries of Defense and State certify that Turkey no longer possesses the S-
400. Turkey has conducted some testing of the S-400 but does not appear to have made the
system generally operational. Turkey may need to forgo possession or use of the S-400 in order to
have CAATSA sanctions removed.
An August 2020 article reported that some congressional committee leaders placed holds on
major new U.S.-origin arms sales to Turkey in connection with the S-400 transaction. The
executive branch customarily defers to such holds, though they are not legally binding.107 Such a
disruption to U.S. defense transactions with Turkey had not occurred since the 1975-1978

Possible F-16 Sales and Congressional Views
Background (Including Turkey-Greece Issues)
In the fall of 2021, Turkish officials stated that they had requested to purchase 40 new F-16
fighter aircraft from the United States and to upgrade 80 F-16s from Turkey’s aging fleet.109
President Biden reportedly discussed the F-16 request with Erdogan during an October 2021 G20
meeting in Rome, indicating that the request would go through the regular arms sales consultation
and notification process with Congress.110 Upgrades of Turkey’s F-16 aircraft to the Block 70/72
Viper configuration would include a new radar, other software and hardware enhancements, and
structural improvements that significantly extend each aircraft’s service life.111
After Russia’s early 2022 invasion of Ukraine, Turkey’s potential to boost NATO’s strategic and
military strengths amid an evolving European security crisis may have increased the
Administration’s interest in moving forward with an F-16 transaction with Turkey. While Turkey
has acted more independently of the West under Erdogan, its sizable military and geographic
location remains important for the alliance.112 Turkey partners in a number of ways with the
United States and its other allies—including by using F-16s in NATO missions based in the Baltic
and Mediterranean Sea regions.113

Responding to criticism of a possible F-16 sale from 53 Members of Congress in a February 2022
letter,114 a State Department official wrote in March that Turkey’s support for Ukraine was “an
important deterrent to malign influence in the region.”115 While acknowledging that any sale
would require congressional notification, the official added, “The Administration believes that
there are nonetheless compelling long-term NATO alliance unity and capability interests, as well
as U.S. national security, economic and commercial interests that are supported by appropriate
U.S. defense trade ties with Turkey.”116
The modernization of much of Turkey’s F-16 fleet could give Turkey time to acquire or design a
more advanced fighter,117 though delivery of new F-16s could face a production backlog.118
According to Lockheed Martin, the F-16 production rate at the Greenville, South Carolina plant is
four aircraft per month, though it plans to increase this rate with a growing list of buyers.119 Other
countries receiving or possibly receiving new or upgraded F-16Vs include Greece, Taiwan,
Singapore, South Korea, Morocco, Bahrain, Jordan, Bulgaria, the Philippines, and Slovakia.120
Once recent contracts for Jordan and Bulgaria finalize, Lockheed will have a backlog of 148
aircraft.121 Based on current production rates, it could take three years or more for Turkey to start
accepting delivery of new F-16Vs.
If unable to upgrade their F-16 fleet, Turkish officials have hinted that they might consider
purchasing Western European alternatives.122 Turkey is reportedly exploring Eurofighter
Typhoons as a potential alternative to F-16s,123 but it is unclear if consortium partner Germany
would approve such a sale.124 Additionally, Turkey’s air force could face difficulties adjusting to a
non-F-16 platform.125 Moreover, European weapons transfers to Turkey could be subject to the
congressional review process described below if such weapons were to include U.S.-origin
defense articles meeting the specified notification threshold.126 Previously, Congress received

notification in connection with some non-NATO countries’ (Saudi Arabia, Kuwait, and Qatar)
proposed purchases of U.S. equipment for Typhoons.127 If Turkey cannot procure F-16s and
encounters obstacles to European alternatives, its next steps toward preserving its military
aviation capabilities and NATO interoperability would be unclear. The State Department’s ICS
for Turkey states:
If NATO and the West continue to not support Turkey’s pursuit of defense modernization,
Turkey may be forced to turn to Russia or China to fulfil those defense capability gaps in
areas where its indigenous defense industry cannot produce the required capability.128
At the end of the June 2022 NATO summit in Spain, where Turkey agreed to allow the Sweden-
Finland accession process to move forward (pending final Turkish ratification) and President
Biden met with President Erdogan, Biden expressed support for selling new F-16s to Turkey as
well as for upgrades. He also voiced confidence in obtaining congressional support.129 However,
SFRC Chairman Bob Menendez has consistently expressed disapproval due to what he has
termed Erdogan’s “abuses across the region.”130
In addition to ongoing U.S.-Turkey tensions regarding Syrian Kurdish groups in northern Syria,
Turkey-Greece disputes regarding overflights of contested areas and other long-standing Aegean
Sea issues (referenced in the text box below) spiked in 2022 and attracted close congressional
attention.131 Erdogan suspended dialogue with Greek Prime Minister Kyriakos Mitsotakis after
Mitsotakis appeared to raise concern about U.S.-Turkey arms transactions while addressing a
May 2022 joint session of Congress.132 In December, the final version of the FY2023 NDAA (P.L.
117-263) excluded a House-passed condition on F-16 sales to Turkey (Section 1271 of H.R.
7900) related to potential overflights of Greek territory. However, the joint explanatory statement
accompanying the NDAA included a provision stating, “We believe that North Atlantic Treaty
Organization (NATO) allies should not conduct unauthorized territorial overflights of another
NATO ally’s airspace.”133 While Turkey-Greece disputes persist, tensions have somewhat
subsided in early 2023. Erdogan and Mitsotakis have renewed contacts in the context of positive
diplomatic momentum from Greek post-earthquake relief assistance to Turkey.134
With U.S. officials already having notified a possible upgrade of F-16s for Greece to Congress in
2017,135 U.S. decisions on bolstering Turkey’s F-16 fleet could have significant implications for

Turkey-Greece-Cyprus Tensions: Background and Some Ongoing Issues139
Since the 1970s, disputes between Greece and Turkey over territorial rights in the Aegean Sea and broader
Eastern Mediterranean have been a major point of contention, bringing the sides close to military conflict on
several occasions. The disputes, which have their roots in territorial changes after World War I, revolve around
contested borders involving the two countries’ territorial waters, national airspace, exclusive economic zones
(including energy claims), islands (and their use for military purposes), and continental shelves (see Figure A-6
and Figure A-7 for maps of some of the areas in dispute).
These tensions are related to and further complicated by one of the region’s major unresolved conflicts, the de
facto political division of Cyprus along ethnic lines that dates from the 1974 military clash in which Turkish forces
invaded parts of the island to prevent the ethnic Greek leadership from unifying Cyprus with Greece. The
internationally recognized Republic of Cyprus (sometimes referred to as Cyprus), which has close ties to Greece,
claims jurisdiction over the entire island, but its effective administrative control is limited to the southern two-
thirds, where Greek Cypriots comprise a majority. Turkish Cypriots administer the northern one-third and are
backed by Turkey, including a Turkish military contingent there since the 1974 clash.140 In 1983, Turkish Cypriot
leaders proclaimed this part of the island the “Turkish Republic of Northern Cyprus,” although no country other
than Turkey recognizes it, and U.N. Security Council Resolution 541 (1983) considered the Turkish Cypriot claim
to be legally invalid.
Turkish officials have complained about a significant new U.S. military presence at the Greek port of
Alexandroupoli (alt. Alexandroupolis), located around 10-15 miles from the Turkish border.141 U.S. officials have
explained that they are using the port as a transit hub to send equipment to allies and partners in the region as
part of a broader NATO response to Russia’s invasion of Ukraine.142 In the March 2022 congressional hearing
testimony mentioned above, Alan Makovsky said that having facilities at Alexandroupoli allows NATO to bypass
logjams or closures of the Straits to transport troops and materiel overland to allies and partners.143 After Turkish
Foreign Minister Mevlut Cavusoglu said in October 2022 that the United States no longer maintains a balanced
approach in the Aegean,144 U.S. Ambassador to Turkey Jeff Flake released a statement saying that there has been

140 Turkey retains between 30,000 and 40,000 troops on the island (supplemented by several thousand Turkish Cypriot

focused on ending Russia’s war in Ukraine.145
Congressional Notification Process
In February 2023, Secretary of State Antony Blinken confirmed the Biden Administration’s
support for and engagement with Congress on a possible sale of F-16 fighter aircraft to Turkey.146
One month earlier, media sources—citing unnamed U.S. officials—reported that the
Administration had provided informal notifications to Congress about possible F-16 sales for
Turkey and possible sales of up to 40 F-35 Joint Strike Fighters to Greece. According to these
reports, the January informal notification on Turkey was for 40 new F-16 Vipers and 79 F-16
Viper upgrade packages, along with 900 air-to-air missiles and 800 bombs, at an estimated total
value of $20 billion.147
After the State Department informally notifies the SFRC and House Foreign Affairs Committee
(HFAC) of a possible Foreign Military Sale (FMS) or Direct Commercial Sale (DCS) of major
defense equipment, articles, and/or services meeting certain value thresholds, the proposed FMS
or DCS requires formal notification to Congress before it can proceed. In general, the State
Department submits the formal notification 20 to 40 days after informal notification.148 This time
period gives the committees opportunity to raise concerns in a confidential “tiered review”
process. If a Member of Congress places a hold (as mentioned earlier, not legally binding) on the
proposed transaction, formal notification usually does not proceed.149 Under provisions of the
Arms Export Control Act (AECA, P.L. 90-629, 82 Stat. 1320), the executive branch can proceed
with a sale—if not blocked by legislation—15 days (for NATO allies like Turkey and Greece)
after formal notification.150
As mentioned above, congressional consideration of the potential F-16 sale to Turkey may
depend on Turkey’s approval of Swedish-Finnish NATO accession.151 Shortly after the reported
informal notifications, the New York Times cited Chairman Menendez as welcoming the F-35 sale
to Greece while strongly opposing the F-16 sale to Turkey, saying:
President Erdogan continues to undermine international law, disregard human rights and
democratic norms, and engage in alarming and destabilizing behavior in Turkey and
against neighboring NATO allies. Until Erdogan ceases his threats, improves his human

rights record at home—including by releasing journalists and political opposition—and
begins to act like a trusted ally should, I will not approve this sale.152
In a March SFRC hearing featuring Secretary Blinken, Chairman Menendez elaborated on
objections he has against various Turkish foreign and domestic policies, and opined that Turkey
does not deserve to receive F-16s unless it addresses some of the issues he mentioned.153
The Administration’s reported informal notifications of potential sales to Turkey and Greece
come amid ongoing tensions between the two countries over maritime boundaries and U.S.
regional involvement (as mentioned above).154 By harmonizing the informal notification on F-35s
for Greece with the one on F-16s for Turkey, the Administration may be seeking to reassure
Greek leaders and popular opinion that the United States is not favoring Turkey over Greece.155
One journalist has argued:
A Greek acquisition of F-35s—coupled with the ongoing procurement of two dozen 4.5-
generation Dassault Rafale F3R fighters from France and the upgrade of the bulk of its F-
16 fleet to the most advanced Block 72 configuration—will give the Hellenic Air Force a
technological edge over its much larger Turkish counterpart. That will remain the case even
if Turkey secures this F-16 deal.156
In response to the news of a possible F-35 sale to Greece, Turkish Foreign Minister Cavusoglu
called on the United States to “pay attention” to the balance of power in the region.157
Congressional committee leaders’ concerns regarding a possible F-16 sale—whether or not tied to
Sweden’s NATO accession prospects—could conceivably persist beyond Turkish elections
scheduled for May. At some point, the Administration may face decisions regarding whether,
when, and how to address congressional concerns, and/or move forward with a formal
notification of the sale.

Turkey (Türkiye): Major Issues and U.S. Relations

Appendix B. Profiles of Selected Turkish Party
Leaders

Recep Tayyip Erdogan—President of Turkey and Leader/Co-Founder of
the Justice and Development Party (AKP)
(pronounced air-doe-wan)
Born in 1954, Erdogan was raised in Istanbul and in his familial hometown of Rize on
the Black Sea coast. He attended a religious imam hatip secondary school in Istanbul.
In the 1970s, Erdogan studied business at what is today Marmara University, became a
business consultant and executive, and became politically active with the different
Turkish Islamist parties led by eventual prime minister Necmettin Erbakan.
Erdogan was elected mayor of Istanbul in 1994 but was removed from office,
imprisoned for six months, and banned from parliamentary politics for religious
incitement after publicly reciting a poem drawing from Islamic imagery. After
Erbakan’s government resigned under military pressure in 1997 and his Welfare Party
was disbanded, Erdogan became the founding chairman of the AKP in 2001. The AKP

won a decisive electoral victory in 2002, and has led the government ever since. After
the election, a legal change allowed Erdogan to run for parliament in a 2003 special
election. After he won, Erdogan replaced Abdul ah Gul as prime minister.
Erdogan and his personal popularity and charisma have been at the center of much of
the domestic and foreign policy change that has occurred in Turkey since he came to
power. Erdogan became Turkey’s first popularly elected president in August 2014 and
won reelection to a newly empowered presidency in June 2018. Many observers
assess that he seeks to consolidate power and to avoid the reopening of corruption
cases that could implicate him and close family members or associates.
Kemal Kilicdaroglu—Leader of the Republican People’s Party (CHP)
(kuhl-utch-dahr-oh-loo)
Born in 1948 in Tunceli province in eastern Turkey to an Alevi (religious minority
with some relation to Shia Islam) background. Kilicdaroglu is the leader of the CHP,
which is the main opposition party and traditional political outlet of the Turkish
nationalist secular elite. In recent years, the party has also attracted various liberal and
social democratic constituencies.
After receiving an economics degree from what is now Gazi University in Ankara,
Kilicdaroglu had a civil service career—first with the Finance Ministry, then as the
director-general of the Social Security Organization. After retiring from the civil
service, Kilicdaroglu became politically active with the CHP and was elected to
parliament from Istanbul in 2002. He gained national prominence for his efforts to
root out corruption among AKP officials and the AKP-affiliated mayor of Ankara.
Kilicdaroglu was elected as party leader in 2010 but has since faced criticism for the
CHP’s failure to make electoral gains at the national level. The CHP made notable
gains—particularly in Istanbul and Ankara mayoral races—in 2019 local elections.
Devlet Bahceli—Leader of the Nationalist Action Party (MHP)
(bah-cheh-lee)
Born in 1948 in Osmaniye province in southern Turkey, Bahceli is the leader of the
MHP, which is the traditional Turkish nationalist party of Turkey that is known for
opposing political accommodation with the Kurds.
Bahceli moved to Istanbul for his secondary education, and received his higher
education, including a doctorate, from what is now Gazi University in Ankara. After a
career as an economics lecturer at Gazi University, he entered a political career as a
leader in what would become the MHP. He became the chairman of the MHP in 1997
and served as a deputy prime minister during a 1999-2002 coalition government. He

Turkey (Türkiye): Major Issues and U.S. Relations

Meral Aksener—Founder and Leader of the Good (Iyi) Party
(awk-sheh-nar)
Born in 1956 in Izmit in western Turkey to Muslims who had resettled in Turkey from
Greece, Aksener is the founder and leader of the Good Party. She founded the party
in 2017 as an alternative for nationalists and other Turks who oppose the MHP’s
alliance with Erdogan.
Aksener studied at Istanbul University and received a doctorate in history from
Marmara University, becoming a university lecturer before entering politics. She was
first elected to parliament in 1995 with the True Path Party, and served as interior
minister in the coalition government that was ultimately forced from office in 1997 by
a memorandum from Turkey’s military. She served in parliament with the MHP from

2007 to 2015 and served for most of that time as deputy speaker.
Aksener became a forceful opponent of Erdogan after the MHP agreed in 2016 to
provide him the necessary parliamentary support for a constitutional referendum
establishing a presidential system of government. She left the party and campaigned
vigorously against the proposed changes, which won adoption in 2017 despite the
controversy that attended the vote. After founding the Good Party, she ran as its
presidential candidate in the 2018 elections.
