On January 15, 1973, President Nixon announced the suspension of offensive actions against North Vietnam. On January 23, Kissinger and Tha met again and signed a contract essentially identical to that of three months earlier. The agreement was signed by the heads of the official delegations on 27 January 1973 at the Majestic Hotel in Paris. Nixon had obtained Thieus` respect for the agreement through a series of letters and envoys that all promised U.S. military support in the event of a North Vietnamese violation of the agreements. For example, on November 14, 1972, Nixon Thieu wrote, “I reiterate my personal assurance that the United States will respond very quickly and quickly to any violation of the agreement.” Both sides saw this as the B-52`s new commitment to fight. In the end, these commitments were not met because of a combination of factors – domestic and Congressional reluctance to get back to war in war, economic constraints and ultimately the Watergate scandal that weakened and hijacked Nixon. After reconstituting their troops and improving their logistics system, North Vietnamese forces launched a large-scale offensive in the Central Highlands in March 1975. On April 30, 1975, NVA tanks rolled through the gate of the presidential palace in Saigon and ended the war. According to Finnish historian Jussi Hanhimki, South Vietnam was put under pressure because of the triangular diplomacy that isolated it to accept an agreement that virtually ensured its collapse. During the negotiations, Kissinger stated that 18 months after an agreement, the United States would not intervene militarily, but that it could intervene before. In the history of the Vietnam War, this has been described as a “decent interval.”  In March 1958, Dr. Charles David Keeling began regularly measuring the amount of carbon dioxide in the atmosphere at the Mauna Loa Observatory in Hawai`i. Over the next few years, his research will show what is now known as the keeling curve: a diagram of … Read more In the coming years, the prolonging of the war, the high number of American casualties and the revelation of U.S. involvement in war crimes, such as the My Lai massacre, have helped many people in the United States turn against the Vietnam War. The 1968 Ttet Communist Offensive dashed U.S. hopes of a swift end to the conflict and spurred U.S. resistance to war.
In response, Johnson announced in March 1968 that he would not seek re-election, citing his responsibility to create a dangerous national division over Vietnam. He also authorized the launch of peace talks. When Thiu, who had not even been informed of the secret negotiations, presented the draft new agreement, he was furious with Kissinger and Nixon (perfectly aware of South Vietnam`s negotiating position) and refused to accept them without substantial changes. He then gave several public radio speeches, saying that the proposed agreement was worse than it actually was. Hanoi was stunned because he believed he had been deceived by Kissinger in a propaganda tour. On 26 October, Radio Hanoi provided important details on the draft agreement. Both sides agreed to the withdrawal of all foreign troops from Laos and Cambodia and the banning of bases and troop movements by these countries. It was agreed that the DMZ would remain a provisional demarcation line on the 17th parallel, with possible reunification of the country “by peaceful means”. An international monitoring commission of Canadians, Hungarians, Poles and Indonesians would be set up, with 1,160 inspectors overseeing the agreement.
