• D. Vietnamization

Answer: (D)

Vietnamization was the policy of gradually withdrawing American troops and replacing them with South Vietnamese forces. It was crafted under President Nixon as a way to wind down U.S. involvement in Vietnam while still supporting South Vietnam in the fight against the Viet Cong and North Vietnamese forces. The idea was to build up the South Vietnamese Army so they could take on more combat duties, with the United States providing training, equipment, and air support, rather than large-scale ground troops. This approach contrasted with earlier strategies that relied on sending more American soldiers to fight, and it aimed to allow the U.S. to claim it was ending its direct military involvement while still aiming to preserve a non-communist South Vietnam. The other terms describe different concepts: containment is about stopping the spread of communism broadly; detente is about easing tensions with rival powers; escalation means increasing U.S. military involvement, not reducing it.
