Answer:
The Vietnam War
Step-by-step explanation:
Ending United States involvement in the Vietnam War was a large issue in the 1968 presidential election. Both candidates vowed that they would find a way to bring U.S. troops home. When Nixon took office, he announced a plan known as "Vietnamization". This plan would entail having American troops train and equip South Vietnamese soldiers. After the Vietnamese soldiers had been trained, the American troops would withdraw from Vietnam.
