Peace treaty the United Nations headquarters. Famous examples include the Treaty of Paris (1815), signed after Napoleon's defeat at the Battle of Waterloo, and the Treaty of Versailles, formally ending the First World War conflict between Germany and the Western Allies. This is held to have ended World War I completely, but in fact that did not happen until the Allies concluded peace with the Ottoman Empire in 1920 through the Treaty of Sèvres. The Versailles treaty is possibly the most notorious of peace treaties, in that it is "blamed" by many historians for the rise of National Socialism in Germany and
1962 in the Vietnam War military involvement in South Vietnam, provided that the government did not include President Diệm. That same month, North Vietnamese official Lê Duẩn instructed the leadership of the Viet Cong to avoid escalating the war by attacking cities as that might cause the United States to intervene in the war. The National Liberation Front in South Vietnam proposed to end the war in South Vietnam with a ceasefire, the withdrawal of American soldiers, and the creation of a coalition government of all factions pending elections. South Vietnam would become a neutral country, as were Cambodia and Laos, guaranteed by international treaty.
