In the Red Sea, the Iran-supported Houthi militia in Yemen has attacked commercial vessels transiting the Bab al Mandab strait, leading several major shipping companies to suspend or reroute cargoes at considerable cost.

homes in the north.13 Since the IDF moved into southern Gaza in early December, its strikes and
calls for people to evacuate some areas have triggered additional displacement within the south,
including from places that had been accommodating thousands of the people who had fled
northern Gaza.14 Israeli aspirations of designating “safe areas” have been met with criticism from
U.N. officials, with one arguing that the pace of Israeli operations in southern Gaza has made no
place safe for civilians, thus leaving any humanitarian plan to protect and aid them “in tatters.”15

Officials from the Palestinian Authority/Palestine Liberation Organization (PA/PLO), based
in the West Bank, appear to be in a difficult position. While they do not endorse Hamas, they
likely remain mindful of the sizable population of Palestinians who support confronting Israel21—
support that could be bolstered by the prisoner releases Hamas secured in late November and by
reactions to civilian suffering.22 Amid rising tensions and violence between Palestinians and
Israelis in the West Bank, President Biden has called for attacks by “extremist settlers” against
Palestinians to stop.23 On December 5, the Department of State announced a “a new visa
restriction policy targeting individuals believed to have been involved in undermining peace,
security, or stability in the West Bank.”24
As civilian casualties have mounted in Gaza, some regional and international actors have grown
more publicly critical of Israeli and U.S. policy. In mid-November, Saudi Arabia hosted a “joint
Arab Islamic” summit, where leaders from the Gulf, Iran, Egypt, Jordan, Turkey, and Syria
called for an end to “Israeli aggression against Gaza,” more humanitarian aid, and a freeze on
international arms exports to Israel.25 Although popular sentiment in Arab states has placed
pressure on their governments to publicly oppose Israeli actions in Gaza,26 one former U.S.
official has said that many Arab leaders have told him that “Hamas must be destroyed in Gaza.”27
On November 15, the U.N. Security Council adopted Resolution 2712, which called for “urgent
and extended humanitarian pauses” and the “immediate and unconditional release of all hostages
held by Hamas and other groups,” and urged all parties to refrain from depriving civilians in Gaza
of “basic services and humanitarian assistance indispensable to their survival.” The resolution

Some open questions include: What would constitute “victory” for Israel in Gaza? What does the
future of Gaza look like? What might be the longer-term ramifications for U.S. priorities such as
Israel’s security, countering the reach of Iran and its allies, and avoiding major war or
humanitarian disaster? Under what circumstances and to what end might U.S.-backed diplomacy
resume between Israel, Palestinians, and Arab states?

Israeli Military Operations and Pauses
The U.S. government has stated its support for military operations by Israel to defend itself in line
with international law, including in Gaza. President Biden, Secretary of State Antony Blinken,
Secretary a grave threat to Israeli strategic sites and population centers.20 U.S. officials are reportedly seeking to help facilitate the withdrawal of Hezbollah forces from border areas to alleviate obstacles to the return of around 80,000 evacuated Israelis to their homes in the north.21 Israeli officials have threatened wider military action to address the issue absent a diplomatic resolution, and the Arouri assassination and other January cross-border strikes by the two sides could affect their calculations regarding whether or not to escalate.22 In the Red Sea, the Iran-supported Houthi militia in Yemen has fired several missiles and drones toward Israel, and has carried out at least 26 attacks on shipping lanes that transit the Bab al Mandab strait.23 Despite repeated international warnings, the Houthis have continued such attacks, forcing, in many cases, the rerouting of commercial shipping around the Cape of Good Hope and away from the Red Sea and Suez Canal. Tensions and violence have continued between Palestinians and Israelis in the West Bank since October 7. West Bank-based officials from the Palestinian Authority/Palestine Liberation Organization (PA/PLO) appear to be in a difficult position. While they do not endorse Hamas, they have refrained from publicly condemning it, perhaps because of a perceived spike in West Bank Palestinian support for Hamas that may stem from Hamas’s military actions, the prisoner releases it has secured, and civilian suffering in Gaza.24 U.S. officials and lawmakers have signaled concerns related to Israeli actions in the West Bank that may affect stable living 17 Michael Horovitz, “Expulsion of Hamas leaders from Gaza on the table, PM said to tell hostage families,” Times of Israel, January 3, 2024. 18 Department of State, “Secretary Antony J.

Popular sentiment in Arab states has placed pressure on their governments to oppose Israeli actions in Gaza,28 even though many Arab leaders might welcome an end to Hamas rule there.29 Together with other members of the Organization of Islamic Cooperation, Arab countries have called for an end to “Israeli aggression against Gaza,” more humanitarian aid, and a freeze on international arms exports to Israel.30 On November 15, the U.N.

have to be careful,” and added “The whole world’s public opinion can shift overnight. We can’t

“by the indiscriminate bombing that takes place.”37
Potential Post-Conflict Scenarios
U.S. officials have engaged in diplomatic talks with Israel and other regional partners over the
future governance of post-war Gaza, with some differences emerging among these parties. In
President Biden’s November 19 op-ed, hehe and Administration officials have sought to convince their Israeli counterparts to take steps to minimize casualties, reduce the intensity of their operations, and step up humanitarian aid. In December, President Biden said, “We continue to provide military assistance to Israel … until they get rid of Hamas,”32 while also warning that Israel has started to lose international 25 Department of State, “Announcement of Visa Restriction Policy to Promote Peace, Security, and Stability in the West Bank,” December 5, 2023. 26 Nancy A.

Tensions between supporting domestically legitimate Palestinian self-rule and safeguarding Israel’s capacity to monitor and stifle potential threats may intensify the challenges involved. In November, President Biden articulated the following principles: articulated the following principles:
To start, Gaza must never again be used as a platform for terrorism. There must be no To start, Gaza must never again be used as a platform for terrorism. There must be no
forcible displacement of Palestinians from Gaza, no reoccupation, no siege or blockade, forcible displacement of Palestinians from Gaza, no reoccupation, no siege or blockade,

including interim security measures, and establish a reconstruction mechanism to including interim security measures, and establish a reconstruction mechanism to
sustainably meet Gaza’s long-term needs.sustainably meet Gaza’s long-term needs.38
In October 31 congressional testimony, Secretary Blinken said that if turning Gaza over to the PA
“in one step” cannot happen, “other, temporary arrangements” could involve other regional
countries and/or international agencies.39 Arab government leaders reportedly are resisting U.S.
suggestions that they play a larger role—expressing that they believe Gaza to be “a problem
largely of Israel’s own making.”40
While discussing potential post-conflict scenarios with Blinken in the West Bank on November 5,
PA President Mahmoud Abbas stated the PA’s willingness to “fully assume our responsibilities
within the framework of a comprehensive political solution that includes all of the West Bank,
including East Jerusalem, and the Gaza Strip,”41 suggesting that he expects progress toward
Palestinian statehood in conjunction with any move toward resuming PA governance in Gaza. In
2005, Israel withdrew its military presence from Gaza and ceded control to the PA. Two years
later in 2007, the PA lost its hold on the territory in an armed struggle with Hamas, which was
founded in Gaza in the 1980s and has maintained a considerable base of support there since.

argued that only the IDF (and not an international force) can demilitarize Gaza.43 Netanyahu also
has said that he disagrees with U.S. officials about a post-conflict role for the PA,44 calling instead
for some other “reconstructed civilian authority.”45
U.S. officials reportedly have acknowledged that the PA would need to “undertake major reforms,
purging its aging leaderships, setting a timetable for elections and overhauling its security forces,
in order to be able to step into Gaza.”46 One U.S. official has said that while IDF management of
security is plausible for “at least some period of time” after the conflict, an IDF reoccupation of
Gaza is not “a long-term governance solution.”47 On December 12, President Biden expressed an
interest in persuading Netanyahu to help strengthen and change the PA and be open to a possible
future Palestinian state, despite opposition to it within Netanyahu’s government.48
Questions may persist about the credibility of any post-conflict outcome and major reconstruction
effort that does not provide some form of (1) order and security, (2) Palestinian autonomy
(connected to aspirations for statehood), and (3) Israeli capacity to monitor and prevent the rise of
threats. Potential tensions among these three points could intensify challenges that actors taking
responsibility for Gaza would face. It is also unclear whether or not such an outcome can be
credible without some continuity in personnel who have run key civil services under Hamas rule.35 PA President Mahmoud Abbas has indicated that the PA would only govern Gaza—which Hamas forcibly seized from the PA in 2007—in the context of significant progress toward establishing a Palestinian state in the West Bank and Gaza, with a capital in East Jerusalem.36 Secretary Blinken has indicated that such progress is unlikely to be easy or “happen overnight.”37 U.S. and PA officials have reportedly discussed possible mechanisms for improving PA institutions, leadership, and domestic legitimacy. Some leading Palestinian figures argue that the PA cannot be strengthened via reforms without Israel granting it greater control over its revenues and security.38 Prime Minister Netanyahu has insisted that only Israel can demilitarize Gaza, and openly opposes the PA returning, purportedly because of rhetorical and financial support the PA provides for terrorism.39 Netanyahu’s position may stem partly from concerns that a return to PA governance in both the West Bank and Gaza could increase international pressure on Israel to accept a two-state solution. He also may calculate that his opposition to PA rule might rally domestic support for him and the ultra-nationalist figures in his government. The significant dip in Netanyahu’s public approval rating since the October 7 attack could lead to his government’s collapse and new Knesset elections sometime in 2024.40 Some of Netanyahu’s advisers may be signaling openness to the possibility of a future role in Gaza for a reformed PA.41 Prospects for any Hamas role in 33 White House, “Remarks by President Biden at a Campaign Reception,” December 12, 2023. 34 White House, “Press Briefing by Press Secretary Karine Jean-Pierre and NSC Coordinator for Strategic Communications John Kirby,” January 3, 2024. 35 Joe Biden, “The U.S. won’t back down from the challenge of Putin and Hamas,” Washington Post, November 18, 2023. 36 Additionally, PA Prime Minister Muhammad Shtayyeh has reportedly said that the PA would be prepared to govern Gaza only if there is a complete Israeli military withdrawal.

It is unclear whether or not the parties can move from the starting points discussed above to compromises on fundamental aspects of post-conflict governance and security. In early January, Defense Minister Gallant proposed a plan for eventual Palestinian civil administration in Gaza that would (1) maintain existing Palestinian administrative mechanisms, with officials and local clans unaffiliated with Hamas; (2) give Israel broad responsibility to prevent security threats against Israel, including via coordination with Egypt at its border with Gaza; and (3) empower a multinational task force (featuring the United States and some European and Arab states) on aspects of civil affairs and economic recovery.43 • Role of PA security forces. Reportedly, “U.S. and Palestinian officials have discussed a plan to retrain 1,000 former [PA] security forces officers in Gaza and a further 3,000 to 5,000 in the West Bank who would work in Gaza after the war,”44 with training presumably under the auspices of the U.S. Security Coordinator for Israel and the Palestinian Authority (USSC).45 • Arab states’ role. Egypt, Jordan, and Arab Gulf states may be reluctant to help with efforts to transition Gaza (by contributing troops, advisers, or funding) toward PA self-rule or help with reconstruction if doing so might be perceived domestically and internationally as enabling indefinite Israeli occupation. Thus, Arab state participation may depend on diplomatic progress toward Palestinian statehood.46

.69 In an early January press conference, a State Department spokesperson remarked that while the United States has seen Israel “take additional measures to deconflict sites,” the “results continue to be – to not match where the Israeli intentions are.”70 In mid-December 2023, CNN reported that a U.S. intelligence assessment compiled by the Office of the Director of National Intelligence concluded that “40-45% of the 29,000 air-to-ground munitions Israel has used [in Gaza since October 7] have been unguided.”71 A Wall Street Journal report from late December investigating a bombing in which Israel killed a senior Hamas commander and 126 other individuals, concluded that while Israeli commanders attempted to limit collateral damage, the bombing of underground tunnels also brought down buildings standing above.72 In a December video, Israel Air Force (IAF) Chief of Staff Brig. Gen. Omer Tischler described the principles IAF officers are instructed to follow when planning potential air strikes.73 Congress may debate end-use monitoring (EUM) requirements for U.S. defense articles in the Congress may debate end-use monitoring (EUM) requirements for U.S. defense articles in the

In summer 2023, the Department of State announced the formation of the Civilian Harm Incident
Response Guidance (CHIRG), a process whereby U.S. officials will “investigate reports of
civilian harm by partner governments suspected of using U.S. weapons and recommend actions
that could include suspension of arms sales.”79 According to DOD, Civilian Harm Mitigation and
Response Officers (CHMROs) are actively monitoring reports of civilian casualties in Gaza.
Subsequent media reports and reports by human rights groups have called into question the ability
or willingness of the Administration to actively monitor Israel’s use of U.S.-supplied military
equipment.80 According to Mira Resnick, the Deputy Assistant Secretary for Regional Security at
the State Department’s Bureau of Political-Military Affairs, “This is an extremely challenging
