The Logic of U.S.Conduct in Responding to International Security
The core objective of the U.S.response to international security issues aims at maintaining its"dominant position"in the international order.When the response to international security issues is conducive to the maintenance of the primacy,the policy of multilateralism is adopted;while it is not conducive to the maintenance of the dominant position,the"nature of the issue"would determine which policy to be selected.The nature of the issue consists of two sub-factors:threat perception and threat definition.Threat perception acts as the primary influence factor determining the U.S.response to international security issues.When U.S.policymakers have a high threat perception of some specific international security issues,they prefer to take unilateralist actions;when the threat perception is low,an isolationist policy would be applied with the reduction of international participation and avoids international responsibility.As the secondary influence factor,threat definition shapes U.S.policy choices along with threat perception.When threat perception is high and threat definition undermines the pillars of international order,the United States would normally adopt a defensive unilateralist policy;when threat perception is high and threat definition does not undermine the pillars of international order,it tends to adopt an offensive unilateralist policy.When the United States responds to international security issues,the idea of maintaining a primacy runs counter to the concept of international security governance,making it difficult to translate its desire to maximize its interests and the rules into a foundational consensus;if it cannot be transformed into a basic consensus,the United States would take actions that are contrary to the norms of international relations and international law,just in order to maintain its primacy.
