Congressional Restrictions on U.S. Military Operations in Vietnam, Cambodia, Laos, Somalia, and Kosovo: Funding and Non-Funding Approaches [January 16, 2007] [open pdf - 188KB]
From the Summary: "The main body of this report is a series of tables and an appendix that summarize and cite bill language that was intended to end or restrict U.S. military operations in Indochina between 1970 and 1973, in Somalia in 1993, and in Kosovo in 1999. The report covers enacted provisions or those where there were roll call votes but the provision was not ultimately enacted. The first table outlines proposals that restrict funding and the second table describes other types of restrictions. Of 21 proposals to restrict funding for military operations that were considered by Congress, 5 were enacted. In the case of Indochina, a major demarcation was the signing of the Vietnam peace accords and a cease-fire agreement between the United States and North Vietnam in January 1973 that required the total withdrawal of U.S. troops by March 1973. Congress continued to provide funds for U.S. troops as levels fell from a peak of 539,000 in June 1969 to 21,500 in January 1973. […] Congress also considered non-funding approaches that urged the President to withdraw forces, negotiate or terminate military operations, seek congressional authorization for military operations, or set a date for U.S. troop withdrawals. Another approach was congressional repeal of the August 1964 Tonkin Gulf Resolution, which authorized the President to use military force in Vietnam."
