The NATO headquarters are located in Brussels, Belgium, while the headquarters of Allied Command Operations is near Mons, Belgium.
Since its founding, the admission of new member states has increased the alliance from the original 12 countries to 30. The most recent member state to be added to NATO was North Macedonia on 27 March 2020. NATO currently recognizes Bosnia and Herzegovina, Georgia, and Ukraine as aspiring members. An additional 20 countries participate in NATO's Partnership for Peace programme, with 15 other countries involved in institutionalized dialogue programmes.
