In International Relations, security perception has changed after 9/11 Events and with the transition from bi-polar system to uni-polar system USA starts to put its increasing weight into the world diplomacy as an only super power. As a result of rapid economic progress in Asya Pasifik region, global political and economic weight passed through Atlantic region to Pasific region. These developments drew US attention to this region. My thesis consists of three sections.
