Final answer:
Yes, Vietnamization was Nixon's strategy to train South Vietnamese forces and withdraw U.S. troops, aimed at achieving 'peace with honor.' It is a true statement.
Step-by-step explanation:
The statement that Vietnamization was Nixon's idea and it promoted the buildup and training of South Vietnamese forces while the U.S forces were extracted from Vietnam is true. Vietnamization was President Nixon's strategy of escalating aerial attacks while increasingly withdrawing US ground troops, with the hope that the South Vietnamese army could eventually defeat the North Vietnamese through U.S. military aid.
This plan included a substantial increase in the training and equipment of South Vietnamese forces and was part of Nixon's broader goal to achieve what he termed 'peace with honor,' ensuring the U.S. would withdraw its troops while attempting to preserve South Vietnam's government and U.S. dignity at the negotiation table.
