 In 1949 Sweden chose not to join NATO and declared a security policy aiming for non-alignment in peace and neutrality in war. A modified version now qualifies non-alignment in peace for possible neutrality in war. This position was maintained without much discussion during the Cold War. Since the 1990s however there has been an active debate in Sweden on the question of NATO membership in the post – Cold War world. These ideological divides were visible in November 2006 when Sweden could either buy two new transport planes or join NATO's plane pool, and in December 2006, when Sweden was invited to join the NATO Response Force. Sweden have been active participants in NATO-led missions in Bosnia (IFOR and SFOR), Kosovo (KFOR), Afghanistan (ISAF) and Libya (Operation Unified Protector).
