Forty years ago today, Senators Frank Church (D, Idaho) and John Sherman Cooper (R, Kentucky) put before the United States Senate an amendment to the Foreign Military Sales Act of 1970 which, if passed, would ban the use of any US funds for combat in or bombing of Cambodia. Debate continued until the amended bill passed on June 30, the date on which Nixon had promised to end the invasion of Cambodia.
The Cooper-Church Amendment was a clear sign that dissatisfaction with the prolonged and catastrophic war in Southeast Asia was finally moving Congress to act. But the more immediate impetus for the bill was the great turmoil which had erupted on the country’s campuses, and the panic it had awakened in the hearts of America’s rulers.
