Oceanic military forces have played minor roles in numerous conflicts outside Oceania since 1945. The region's two biggest military powers, Australia and New Zealand, sent troops to fight in the Korean, Vietnam, Gulf and Afghanistan Wars, and Australia also participated in the Iraq War. Neither is a major military power in world terms, preferring to join with coalition operations, but both possess modern and well trained defense forces. Both have made significant contributions to international peacekeeping operations, although their focus has tended to be within Oceania.
