The North Atlantic Treaty Organisation (NATO, or the Atlantic Alliance) was founded in 1949 and has its headquarters in Brussels. It has 19 members: the EU Member States (with the exception of Austria, Finland, Ireland and Sweden), Canada, the United States, Iceland, Norway and Turkey, and ,since 12 March 1999, Poland, Hungary and the Czech Republic.
The policy of the Union respects the obligations on certain Member States arising out of NATO membership and is compatible with the common security and defence policy agreed in NATO. The Declaration on Western European Union annexed to the EU Treaty clarifies future relations between NATO and the WEU, which serves as the defence arm of the Union and as a means of strengthening the European pillar of the Atlantic Alliance.
