The North Atlantic Treaty Organization ^Investor

North Atlantic Treaty Organization is a military alliance formed between 26 nations to enforce the North Atlantic Treaty of 1949. It provides a unique link between these two continents for consultation and cooperation in the field of defense and security, and the conduct of multinational crisis-management operations.

NATO was originally formed to combat the spread of communism, but has grown since then to provide a mutual defense from external threats. As of 2008, NATO is made up of these nations: Belgium, Bulgaria, Canada, the Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Turkey, United Kingdom, and the United States.
