How did Nixon redirect the peace process when he became president?

When Richard Nixon became president, he shifted the peace process in Vietnam by implementing a strategy known as "Vietnamization," which aimed to reduce American troop involvement while increasing the responsibility of South Vietnamese forces in combat. Nixon also engaged in secret negotiations with North Vietnam, seeking a way to end the war while preserving U.S. credibility. Additionally, he expanded the conflict into neighboring countries like Cambodia, which he justified as necessary to protect American interests and stabilize the region. This approach sought to create conditions for a negotiated settlement while maintaining a tough stance against communism.
