Richard Nixon’s presidential campaign led many to conclude he had a secret plan to end the Vietnam war. Some historians believe he was actually determined to win the war. Others say he planned a negotiated withdrawal from the beginning. We do know he had a secret. He sabotaged Johnson’s peace talks to prevent an agreement from threatening his election.

Acting on a tip, President Johnson ordered an FBI wiretap on South Vietnamese Embassy phones. This confirmed that Nixon was indeed interfering with the peace talks. Nixon had sent an emissary to tell President Thieu of South Vietnam not to sign the peace agreement that President Johnson was currently negotiating. When Nixon became President, he negotiated a peace deal that left Thieu in a more powerful position.

When he left the White House, Johnson instructed his National Security Adviser Walt Rostow to take the files related to Nixon’s interference with the peace talks. In 1973 Rostow gave them to the Johnson Presidential Library with instructions not to open them for 50 years. However, they were opened in 1994, and most of the documents have since been declassified.

Johnson never went public with Nixon’s meddling, believing it would have thrown the country into turmoil.

The National Archives

DocsTeach is a product of the National Archives education division. Our mission is to engage, educate, and inspire all learners to discover and explore the records of the American people preserved by the National Archives.

The National Archives and Records Administration is the nation's record keeper. We save documents and other materials created in the course of business conducted by the U.S. Federal government that are judged to have continuing value. We hold in trust for the public the Declaration of Independence, the Constitution, and the Bill of Rights — but also the records of ordinary citizens — at our locations around the country.
