2016年1月和2月朝鲜先后进行的第四次核试验和远程导弹发射使得韩美之间有关“萨德”反导系统部署的谈判最终公开化。究其原因，背后不仅暗藏有美国的政治动机和军事意图，而且也反映出韩国欲部署“萨德”反导系统的考虑。不过，对韩国而言，虽然“萨德”反导系统可弥补韩国本国导弹防御系统的不足，但是其用于应对朝鲜半岛突发事件的实际效用有限，并非可靠的国家安全保障手段，要实现最终部署亦面临诸多挑战和阻力。韩国应该慎重对待“萨德”反导系统的部署问题，做出有利于中韩关系的战略选择。
Since 2015，we see an endless rumors of secret negotiations on deploying “THAAD” anti-missile system between the ROK and the USA，especially after the ROK chose to join China’s leading and building the AIIB in March，the attitudes of the ROK and the USA governments on deploying “THAAD” anti-missile system within the territory of the ROK are different several times. Its reasons are not only the USA’s political motives and military intentions，but also the ROK planning to deploy “THAAD” anti-missile system. But for the ROK，although “THAAD” anti-missile system can make up for the inadequacy of the Korean national missile defense system，but also faced with many challenges and resistance. The ROK should treat the deployment “THAAD” anti-missile system with caution，make the right strategic choice.
