In January 1969, there were no U.S. relations with China, no arms control talks in progress with the U.S.S.R., no peace process in the Middle East, there were race or anti-war riots almost every week all over the United States, and the country had been shaken by the assassinations of Martin Luther King and Robert Kennedy (both in their early 40s). LBJ could not go anywhere in the country without demonstrations, as students occupied universities and the whole country was in tumult.
Four years later, Nixon had withdrawn from Vietnam, preserving a non-communist South Vietnam, which had defeated the North Vietnamese and Viet Cong in April 1972 with no American ground support, though heavy air support. He had negotiated and signed the greatest arms control agreement in world history with the Soviet Union, founded the Environmental Protection Agency, ended school segregation and avoided the court-ordered, Democratic Party-approved nightmare of busing children all around metropolitan areas for racial balance, and there were no riots, demonstrations, assassinations or university occupations. He started the Middle East peace process, reduced the crime rate and ended conscription.
For all of these reasons, he was re-elected by the greatest plurality in American history, 18 million votes, and a percentage of the vote (60.7) equaled only by Lyndon Johnson in 1964 and Franklin D. Roosevelt in 1936. His term was rivaled only by Lincoln’s and FDR’s first and third terms as the most successful in U.S. history.
