With Donald Trump’s victory in the U.S. presidential election, America First is expected to resurface, signaling a second seismic shift in the international security landscape. Trump, who views alliances from a transactional perspective, has made it clear that the United States will no longer bear the sacrifices of being the world’s sole policeman. His administration is likely to prioritize clear national interests over the abstract goal of restoring U.S. leadership. By operating under the framework of power politics among great powers and striving for “fair” alliances, Trump aims to maintain the United States’ leading position in the international community while pursuing economic prosperity.

On the Korean Peninsula, Trump’s security policy may retain its fundamental stance, but it differs significantly in implementation. While the Korean Peninsula remains subordinate to China policy, the conditions have shifted due to South Korea’s expanded international role, North Korea’s strengthened nuclear capabilities, and the Ukraine war. Above all, the South Korean government now pursues a Korea-led response in negotiations and strategies with North Korea, contrasting with the situation during Trump’s first term. If the United States unilaterally advances its inter-Korea policy, it could lead to conflicts with its ally, South Korea.
