Abstract：In February 2018, the Pyeongchang Winter Olympic Games were taken as an opportunity for the DPRK and the ROK to approach each other. On April 27th, a historic summit was held in Panmunjom and leaders of the two sides released the Panmunjom Declaration, which initiated the contact between the US and the DPRK. On June 12th, a summit between the US and the DPRK was held in Singapore, and tensions on the peninsula have been eased since then. In the context of geopolitical competition among major powers, the core of the situation on the Korean Peninsula lies in the nuclear issue. Whether Trumps policy towards the DPRK is sustainable or expedient remains unknown. Based on his political tendency exhibited since the presidential election in 2016, the paper proposes that Trumps policy towards the DPRK would be different with the established foreign policy of the US since he is prone to make some breakthroughs in the nuclear issue. Nevertheless, he is unlikely to compromise in lifting the sanctions and military pressure on the DPRK. This paper traces the evolution of Trumps DPRK policy, analyzes its major reasons, and made predictions on possible choices of President Trump. In conclusion, any change of Trumps policy towards the DPRK will make both negative and positive impacts on the situation on the Korean Peninsula, to which the countries concerned should pay close attention and take timely action.
