 The IDF was downsized after the end of the Cold War and the U.S. Air Force maintained four to six interceptor aircraft at the Naval Air Station Keflavik, until they were withdrawn on 30 September 2006.Since May 2008, NATO nations have periodically deployed fighters to patrol Icelandic airspace under the Icelandic Air Policing mission.Iceland supported the 2003 invasion of Iraq despite much domestic controversy, deploying a Coast Guard EOD team to Iraq, which was replaced later by members of the Iceland Crisis Response Unit.
