NATO Founded: Twelve Nations Unite Against Soviet Threat
Twelve nations signed the North Atlantic Treaty on April 4, 1949, in Washington, D.C. The core commitment was Article 5: an attack against one member would be considered an attack against all. This collective defense clause remained untested for over fifty years until it was invoked for the first and only time after the September 11, 2001 attacks. The original signatories were the United States, Canada, the United Kingdom, France, Belgium, the Netherlands, Luxembourg, Norway, Denmark, Iceland, Italy, and Portugal. The treaty was explicitly designed to counter the Soviet Union without naming it. NATO has since expanded to 32 members, and Article 5 remains the most consequential mutual defense commitment in modern history.
