In what year did the Case-Church Amendment end U.S. involvement in Vietnam?

• A. 1969
• B. 1973
• C. 1968
• D. 1975

Answer: (B)

This item tests how a legislative action ended U.S. involvement in Vietnam. The Case-Church Amendment prohibited further U.S. funding for combat activities in Indochina and set a timetable that effectively halted American military actions, pushing the United States toward complete withdrawal. It was enacted in 1973, after the Paris Peace Accords had begun to wind down the conflict and paved the way for withdrawal of U.S. troops. The other years don't reflect this specific legislative move that cut off funding for further combat. So, the year tied to the end of U.S. involvement due to this amendment is 1973.
