Institutions of the EU include the European Commission, the Council of the European Union, the European Council, the Court of Justice of the European Union, the European Central Bank, the Court of Auditors, and the European Parliament. The European Parliament is elected every five years by EU citizens. The EU's de facto capital is Brussels." [European Union. Wikipedia]
"The principal military alliance in Europe remains NATO, which includes 21 of all EU member states as well as other non-EU European countries, Turkey, the United States and Canada." [Military of the European Union. Wikipedia]
"The North Atlantic Treaty Organization (NATO), also called the (North) Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defense in response to an attack by any external party. NATO's headquarters are in Brussels, Belgium, one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009." [NATO. Wikipedia]
