April 4, 1949 - NATO, the North American Treaty Organization, is formed by the United States, Canada, and ten Western European nations (Belgium, Denmark, France, Iceland, Italy, Luxembourg, Netherlands, Norway, Portugal, United Kingdom). The treaty stated that any attack against one nation would be considered an attack against them all.
It was a necessary step for security in the wake of the end of World War II just passed and the continuously emerging threat of the Cold War on the rise. There had been an attempt already at a treaty that would secure the states of the North Atlantic against attack. The Treaty of Brussels had been signed on March 17, 1948 by Belgium, the Netherlands, Luxembourg, France, and the United Kingdom as a mutual defense pact against the Soviet Union. Eight days later, the Soviet Union issued orders that would restrict military and passenger traffic between the French, British, and American sectors of Germany and Berlin. By June 24, the Berlin blockade was in full force. The Treaty of Brussels was not going to be enough. The power of the nations involved would not be strong enough to counter the Soviet Union.
Secret negotiations on a stronger pact began in 1948, involving the United States, Canada, Portugal, Italy, Norway, Denmark and Iceland. The tenants of the organization were strong. Paramount to the North Atlantic Treaty was the promise that an attack against any one of those who signed would be considered an attack against all. The other nations would respond, either diplomatically or militarily, to assist. During the first year, NATO was predominantly considered a political organization, however, with the outbreak of war on the Korean Peninsula in 1950, that began to change. By January of 1951, General Dwight D. Eisenhower, as Supreme Allied Commander, was placed in charge of the Supreme Headquarters Allied Powers Europe and tasked with devising military plans. Thirty-five divisions would be ready to take action, if necessary, with nuclear weapons used as a threat to insure peace. Military exercises showing the power of the alliance would begin in September 1952.
"By this treaty, we are not only seeking to establish freedom from aggression and from the use of force in the North Atlantic community, but we are also actively striving to promote and preserve peace throughout the world." Harry S. Truman, August 24, 1949.
