Within the Membership Action Plan, the country's cooperation with NATO is structured through the Bosnia and Herzegovina Reform Programme, which outlines the reforms the government intends to undertake and facilitates the provision of support by NATO toward these efforts.
On October 9, 1992, the Security Council passed Resolution 781, establishing a no-fly zone over Bosnia-Herzegovina. In response, on October 16, NATO expanded its mission in the area to include Operation Sky Monitor, which monitored Bosnian airspace for flights from the Federal Republic of Yugoslavia.
A series of grave developments led NATO to intervene in Bosnia in 1995, including war crimes, the genocidal fall of Srebrenica, the taking of UN hostages by Bosnian Serb forces, and breaches of the Geneva Conventions. A NATO military operation was conducted in Bosnia, a country not a member of the alliance.
The unpopularity of NATO among Bosnian Serbs, as a result of its involvement in the 1992–1995 war and its airstrikes against Serbia in 1999 (especially during the Kosovo War of 1999), have contributed to Republika Srpska's continued obstruction of Bosnia's NATO integration progress.
