奥巴马政府时期，美韩联盟得到进一步扩展。在朝核问题陷于僵局的状况下，美韩同盟朝着制度化方向发展。美韩同盟具有超越朝鲜半岛问题的趋势，成为美国亚太“再平衡”战略的重要组成部分。2016年朝鲜第四次核试验为美韩同盟的进一步加强提供了动力。美韩同盟在各个领域中仍存在分歧与矛盾，随着美韩各自国内政治、经济的不断发展，美韩同盟关系在未来将面临一些不确定因素。
During the Obama Administration，US-ROK Alliance experienced further development. With the deadlock of North Korea nuclear issue，US-ROK Alliance moves toward the direction of institutionalization. Aiming to cope with issues beyond ROK-DPRK crisis，US-ROK Alliance is becoming an important part of the US Asia-Pacific rebalance strategy. The fourth nuclear test by DPRK in 2016 undoubtedly reinforced the US-ROK Alliance. But the disputes and contradictions between the US and ROK remain in various fields. With the development of politics and economy both in the US and ROK，the alliance still faces uncertainties in the future.
