List of NATO operations

Although the North Atlantic Treaty Organization (NATO) existed as an alliance and conducted joint military exercises throughout the Cold War period, it engaged in no military operations during this time. All of its military operations occurred in the post-Cold War era. The first of these was in Bosnia, where NATO engaged to an increasing extent. This engagement culminated in NATO's 1995 air campaign, Operation Deliberate Force, which targeted the Army of Republika Srpska, whose presence in Bosnia posed a danger to United Nations Safe Areas. This engagement ultimately helped to bring about the Dayton Accords.

The organization played a prominent role in Afghanistan after the September 11 attacks, when the United States invoked Article 5 of the North Atlantic Treaty, which interprets an external attack on any member to be an attack on all NATO members under the idea of collective defense. NATO has participated in a wide range of roles elsewhere, including relief efforts, counter-piracy, enforcing no-fly zones and naval blockades.

Bosnia and Herzegovina (1992–2004)
NATO was prominent in Bosnia during the early 1990s, and gradually its role became larger with some operations escalating, for instance Operation Sky Monitor turned into Operation Deny Flight which gave NATO "all measures necessary" to enforce a more stringent no-fly zone unlike Sky Monitor during which the no-fly zone was violated over 500 times. It took 46 years after NATO's inception in 1949 for the organization first ever military intervention took place in 1995, Operation Deliberate Force which was targeted the Army of Republika Srpska in Bosnia whose presence posed a danger to designated United Nations "safe areas". The air campaign helped bring about the Dayton Accords.
