Washington: U.S. President Donald Trump's administration has released its new National Security Strategy (NSS), reaffirming his America First policy principles, and calling for South Korea and other allies to increase defense spending and contribute "far more" to "collective defense." According to Yonhap News Agency, the White House unveiled the 33-page document outlining the administration's stance on foreign policy, defense, and economic security, reiterating Washington's calls for allies and partners to undertake greater security burdens. It stresses that "the days of the United States propping up the entire world order like Atlas are over." The document prioritizes preventing a conflict over Taiwan-a self-governing democracy that China regards as part of its territory-while vowing to enforce a "Trump Corollary" to the 1823 Monroe Doctrine. This approach aims to restore American preeminence in the Western Hemisphere, symbolizing a move towards isolationism. Unlike past versions, the latest NSS does not mention North Korea, nor does it include the U.S.'s commitment to the denuclearization of the regime. This omission has raised concerns that the security issue surrounding Pyongyang could be sidelined. The strategy insists on fair treatment in military alliances and trade relations, highlighting that the U.S. will no longer tolerate free-riding, trade imbalances, and predatory economic practices. The administration expects allies to spend "far more" of their GDP on defense to address longstanding imbalances due to greater U.S. spending. South Korea has committed to raising its defense spending to 3.5 percent of its GDP, drawing praise from U.S. Under Secretary of Defense for Policy Elbridge Colby. He noted that South Korea is the first treaty ally outside the North Atlantic Treaty Organization to make such a spending commitment.
