On this day 77 years ago, on March 17, 1948 (February 7, 1948 lunar calendar), the Treaty of Brussels was signed. On March 17, 1948, the Treaty of Brussels was signed. After the end of World War II, with the implementation of the Truman Doctrine and the Marshall Plan, the penetration and expansion of the United States into Western Europe became a reality. Britain took advantage of the growing threat of the Soviet Union to take advantage of the insecurity of Western European countries and speed up the pace of Western European unity. In January 1948, British Foreign Secretary Bevin gave a speech and formally proposed the Western European Union. France, Belgium, the Netherlands, and the four countries responded. On March 5, representatives of Britain, France, Belgium, the Netherlands and the Netherlands held treaty negotiations in Brussels; on the 17th, the foreign ministers of the five countries held the signing ceremony of the Brussels Treaty, which will last for 50 years and enter into force on August 25 of the same year. The highest leading body of the treaty organization is the Foreign Ministers' Consultative Committee. In addition, the Western European Union Defense Committee, the Western Union Staff Department and the Western Union Command Committee were also established. During the formation of the Brussels Treaty, the US government not only actively encouraged, but also expressed that it would start to provide military protection and military assistance to Western Europe. The establishment of the Brussels Treaty Organization is the prelude to the formation of the North Atlantic Military Alliance.
