Nixon and Vietnam
In the 1968 election, Republican Richard Nixon claimed to have a plan to end the war in Vietnam, but, in fact, it took him five years to disengage the United States from Vietnam. Indeed, Richard Nixon presided over as many years of war in Indochina as did Johnson. About a third of the Americans who died in combat were killed during the Nixon presidency.
Insofar as he did have a plan to bring "peace with honor," it mainly entailed reducing American casualties by having South Vietnamese soldiers bear more of the ground fighting--a process he called "Vietnamization"--and defusing anti-war protests by ending the military draft. Nixon provided the South Vietnamese army with new training and improved weapons and tried to frighten the North Vietnamese to the peace table by demonstrating his willingness to bomb urban areas and mine harbors. He also hoped to orchestrate Soviet and Chinese pressure on North Vietnam.
The most controversial aspect of his strategy was an effort to cut the Ho Chi Minh supply trail by secretly bombing North Vietnamese sanctuaries in Cambodia and invading that country and Laos. The U.S. and South Vietnamese incursion into Cambodia in April 1970 helped destabilize the country, provoking a bloody civil war and bringing to power the murderous Khmer Rouge, a Communist group that evacuated Cambodia's cities and threw thousands into re-education camps.
Following his election, President Nixon began to withdraw American troops from Vietnam in June 1969 and replaced the military draft with a lottery in December of that year. In December 1972, the United States began large-scale bombing of North Vietnam after peace talks reach an impasse.
