Alliance Burden Sharing and Stakeholder Cognition:The Evolution of U.S.Asia-Pacific Alliance Cohesion
Since the Trump and Biden administrations,the U.S.has insisted on requesting Japan and South Korea to share more alliance burden.However,under the same circumstances that Japan and South Korea have increased alliance burden sharing,the cohesion of the U.S.-Japan and U.S.-South Korea alliances has suffered great weakening during the Trump administration,but has been significantly restored and even further strengthened during the Biden administration.According to traditional alliance theory,dominant country's maintenance or increase of investment will help preserve and strengthen the cohesion of the alliance,and vice versa.However,the contrast between theoretical assumption and current reality raises a research question:while the dominant country's willingness and ability to share alliance burden decreases,and the subordinate country increases burden sharing,why does the alliance cohesion strengthen instead of weakening?The article aims to establish a theoretical framework based on the concept of stakeholder cognition.By doing empirical research,it was found that,on the premise that Japan and South Korea increased their alliance investment,Trump did not give full strategic commitment to U.S.-Japan alliance and U.S.-South Korea alliance,and did not recognize the value of Japan's and South Korea's role in the alliance,which has seriously reduced the two countries'stakeholder cognition,thereby weakening the cohesion of these two alliances.On the contrary,the Biden administration has not only fully given strategic commitment to the U.S.-Japan alliance and U.S.-South Korea alliance,but also highly recognized the value of Japan's and South Korea's role in the alliance,which has greatly improved the stakeholder cognition of the two countries,thus strengthening the cohesion of these two alliances.
