A Brief Summary of Pro and Con Arguments

Summary
The War Powers Resolution, Public Law 93-148, was enacted by Congress over
the veto of President Nixon on November 7, 1973. Through more than twenty-two years
of experience, the resolution has remained a focus of controversy on the war powers of
the President and Congress under the Constitution.1 Major areas of controversy include
the constitutionality of some provisions, the proper roles for the President and Congress
in entering armed conflicts, the effect on U.S. military operations, and the effectiveness
of the resolution in achieving its purpose of assuring that the collective judgment of the
Congress and the President apply to the introduction of U.S. Armed Forces into
hostilities. In the post-Cold War era, the relationship of the War Powers Resolution to
U.S. participation in military/peacekeeping activities under the auspices of the United
Nations, as well as peacekeeping operations in general have become an issue. This
report lists major arguments for and against the resolution. This report will not be
updated.
