After intensive negotiations between National Security Adviser Henry Kissinger and North Vietnamese Foreign Minister Le Duc Tho, the two sides reached an agreement in October 1972, and Kissinger announced, “Peace is at hand.” But the South Vietnamese raised objections, and the agreement quickly broke down. An intensive 11-day bombing campaign of Hanoi and other North Vietnamese cities in late December (the “Christmas bombings”) was followed by more negotiations, and a new agreement was finally reached in January 1973 and signed in Paris. It included an immediate cease-fire, the withdrawal of all American military personnel, the release of all prisoners of war, and an international force to keep the peace. For their work on the accord, Kissinger and Tho were awarded the 1973 Nobel Prize for Peace (though Tho declined the honors)." But Vietcong entered the Saigon two years later.
