I've got a better idea: Dismantle this old Cold War dinosaur, or at the very least, the United States should withdraw from it, which would undoubtedly lead to its demise anyway.

NATO was formed after World War II to ostensibly protect Western Europe from an invasion by the Soviet Union. The organization was part of the overall Cold War campaign of anti-communist fear-mongering that was used to convert the United States to a massive national-security, military-intelligence nation. 

The Soviet Union, which — let us not forget — was a partner and ally of the United States during World War II, was totally devastated by the end of the war, owing to the massive deadly and destructive invasion of the country by Nazi forces. Thus, the notion that the Soviet Union intended to invade Western Europe was always ridiculous, especially since it was a virtual certainty that the United States would come to the defense of Western Europe. Why would the Soviets want to go to war against the only nation that had nuclear bombs and the willingness to use them against populated cities?
