This is the fundamental characteristic of the international situation. In the five years since September 11, the increase of the terrorist threat has impelled the United States to adjust its global strategy. Unilateralism, with preemptive measures as its core, has reached its zenith and, therefore a host of regional and global contradictions have appeared. This is the main thread of the international situation in the past five years.展开更多
