1972
January 25, 1972 - President Nixon announces a proposed eight point peace plan for Vietnam and also reveals that Kissinger has been secretly negotiating with the North Vietnamese. However, Hanoi rejects Nixon's peace overture.
February 21-28 - President Nixon visits China and meets with Mao Zedong and Prime Minister Zhou Enlai to forge new diplomatic relations with the Communist nation. Nixon's visit causes great concern in Hanoi that their wartime ally China might be inclined to agree to an unfavorable settlement of the war to improve Chinese relations with the U.S.
March 10, 1972 - The U.S. 101st Airborne Division is withdrawn from Vietnam.
March 23, 1972 - The U.S. stages a boycott of the Paris peace talks as President Nixon accuses Hanoi of refusing to "negotiate seriously."
March-September - The Eastertide Offensive occurs as 200,000 North Vietnamese soldiers under the command of General Vo Nguyen Giap wage an all-out attempt to conquer South Vietnam. The offensive is a tremendous gamble by Giap and is undertaken as a result of U.S. troop withdrawal, the strength of the anti-war movement in America likely preventing a U.S. retaliatory response, and the poor performance of South Vietnam's Army during Operation Lam Son 719 in 1971.
Giap's immediate strategy involves the capture of Quang Tri in the northern part of South Vietnam, Kontum in the mid section, and An Loc in the south.
North Vietnam's Communist leaders also hope a successful offensive will harm Richard Nixon politically during this presidential election year in America, much as President Lyndon Johnson had suffered as a result of the 1968 Tet Offensive. The Communists believe Nixon's removal would disrupt American aid to South Vietnam.
March 30, 1972 - NVA Eastertide attack on Quang Tri begins.
April 2, 1972 - In response to the Eastertide Offensive, President Nixon authorizes the U.S. 7th Fleet to target NVA troops massed around the Demilitarized Zone with air strikes and naval gunfire.
April 4, 1972 - In a further response to Eastertide, President Nixon authorizes a massive bombing campaign targeting all NVA troops invading South Vietnam along with B-52 air strikes against North Vietnam. "The bastards have never been bombed like they're going to bombed this time," Nixon privately declares.
April 10, 1972 - Heavy B-52 bombardments ranging 145 miles into North Vietnam begin.

May 8, 1972 - In response to the ongoing NVA Eastertide Offensive, President Nixon announces Operation Linebacker I, the mining of North Vietnam's harbors along with intensified bombing of roads, bridges, and oil facilities. The announcement brings international condemnation of the U.S. and ignites more anti-war protests in America.
During an air strike conducted by South Vietnamese pilots, Napalm bombs are accidentally dropped on South Vietnamese civilians, including children. Filmed footage and a still photo of a badly burned nude girl fleeing the destruction of her hamlet becomes yet another enduring image of the war.

The U.S. will allow North Vietnamese troops already in South Vietnam to remain there, while North Vietnam drops its demand for the removal of South Vietnam's President Thieu and the dissolution of his government.
Although Kissinger's staff members privately express concerns over allowing NVA troops to remain in the South, Kissinger rebuffs them, saying, "I want to end this war before the election."
October 22, 1972 - In Saigon, Kissinger visits President Thieu to discuss the peace proposal.
Meetings between Kissinger and Thieu go badly as an emotional Thieu adamantly opposes allowing North Vietnamese troops to remain indefinitely in South Vietnam. An angry Kissinger reports Thieu's reaction to President Nixon, who then threatens Thieu with a total cut-off of all American aid. But Thieu does not back down. Kissinger then returns to Washington.
October 22, 1972 - Operation Linebacker I ends. U.S. warplanes flew 40,000 sorties and dropped over 125,000 tons of bombs during the bombing campaign which effectively disrupted North Vietnam's Eastertide Offensive.
During the failed offensive, the North suffered an estimated 100,000 military casualties and lost half its tanks and artillery. Leader of the offensive, legendary General Vo Nguyen Giap, the victor at Dien Bien Phu, was then quietly ousted in favor of his deputy Gen. Van Tien Dung. 40,000 South Vietnamese soldiers died stopping the offensive, in the heaviest fighting of the entire war.

December 13, 1972 - In Paris, peace negotiations between Kissinger and Le Duc Tho collapse after Kissinger presents a list of 69 changes demanded by President Thieu.
President Nixon now issues an ultimatum to North Vietnam that serious negotiations must resume within 72 hours. Hanoi does not respond. As a result, Nixon orders Operation Linebacker II, eleven days and nights of maximum force bombing against military targets in Hanoi by B-52 bombers.
December 18, 1972 - Operation Linebacker II begins. The so called 'Christmas bombings' are widely denounced by American politicians, the media, and various world leaders including the Pope. North Vietnamese filmed footage of civilian casualties further fuels the outrage. In addition, a few downed B-52 pilots make public statements in North Vietnam against the bombing.
December 26, 1972 - North Vietnam agrees to resume peace negotiations within five days of the end of bombing.
December 29, 1972 - Operation Linebacker II ends what had been the most intensive bombing campaign of the entire war with over 100,000 bombs dropped on Hanoi and Haiphong.
