In what year did the United States begin a notable policy shift toward de-escalation and Vietnamization?

• A. 1969
• B. 1966
• C. 1973
• D. 1963

Answer: (A)

The question tests recognizing when the United States started shifting from heavy escalation to de-escalation and Vietnamization. In 1969, after Richard Nixon took office, the administration announced a new approach: gradually withdrawing U.S. troops and turning more fighting responsibilities over to South Vietnamese forces (Vietnamization), while pursuing negotiations in Paris to achieve a settlement. This marked a clear move away from the prior pattern of large-scale American troop increases and direct ground combat involvement, aiming to reduce U.S. fighting without a definitive loss of South Vietnamese capability.

Earlier years fit different phases: 1963 and 1966 come from the escalating U.S. commitment under Kennedy and Johnson, not the de-escalation policy; 1973 is when direct U.S. combat involvement effectively ended with the Paris Peace Accords, but the shift toward de-escalation and Vietnamization was already underway starting in 1969.
