Final answer:
Presidents Lyndon Johnson and Richard Nixon had different approaches to the Vietnam War. Johnson escalated US involvement, but later sought to withdraw troops. Nixon implemented Vietnamization and escalated bombing campaigns.
Step-by-step explanation:
Presidents Lyndon Johnson and Richard Nixon differed in their approaches to the Vietnam War in several ways. Johnson initially escalated US involvement in the war, increasing troop levels and launching a sustained bombing campaign. However, by the end of his term, he began negotiations with North Vietnam and signaled a desire for US forces to be withdrawn.
In contrast, Nixon implemented a strategy called Vietnamization, which involved gradually transferring the responsibility for fighting the war to the South Vietnamese while reducing American troop presence. Additionally, Nixon secretly derailed Johnson's peace talks and escalated the bombing campaigns in Laos and Cambodia.
