Trump Gutted the Joint Military Exercises Defending Ally South Korea — Hours Before They Began — Because Kim Jong Un Is "Unthreatening and Respectful" and "I Understand Him," and to Punish Seoul for Refusing to Join His Iran War, Rewarding the Nuclear Dictator Who Flatters Him at a Democratic Ally's Expense

The point of a defense alliance is to be ready when the threat comes, and to make the threat think twice by being ready. Trump just weakened one of America's oldest alliances for the opposite reason: because the threat — a nuclear-armed dictator — had been nice to him.

What he did

On August 16, 2026, hours before the drills were to start, Trump directed Defense Secretary Pete Hegseth to "substantially reduce" the Ulchi Freedom Shield exercises with South Korea — the long-planned joint drills involving roughly 18,000 South Korean troops that keep the U.S.-South Korea mutual-defense treaty prepared for a North Korean attack. He gave two reasons:

• His "very good relationship" with North Korea's Kim Jong Un
• South Korea's refusal to join his war in Iran

The exercises, Trump wrote, "send a signal that is totally inappropriate and hostile, to a Country that, as long as Donald J. Trump has been President, has been unthreatening and respectful." He praised a "very wise and reasoned" Kim decision and delivered the line that captures the whole relationship: "I understand him. He understands me."

Every premise is wrong

Kim is not "unthreatening and respectful." He has declared that North Korea is and always will be a nuclear power, continues to test ballistic missiles, and has called South Korea a "hostile enemy." Treating him as a benign partner because he refrains from personally insulting Trump mistakes flattery for peace.

The drills are not a provocation. Ulchi Freedom Shield and exercises like it are the ordinary, defensive readiness training of a mutual-defense treaty that has kept the peace on the Korean peninsula for seventy years. Scaling them back does not calm a hostile North Korea; it degrades the alliance's ability to respond if that North Korea — the one with the growing nuclear arsenal — decides to move.

The punishment logic is worse than the appeasement. Trump tied the cut, in part, to South Korea's refusal to join his war in Iran — a conflict on the other side of the world that has nothing to do with the defense of the Korean peninsula. That treats a treaty ally's security as leverage: fight in my war, or I'll pull back the forces that help protect you. It tells every U.S. ally that the American security guarantee is now conditional on following Trump into whatever war he chooses.

What Kim got, and what it signals

Kim Jong Un understood years ago what moves this president: not concessions, not denuclearization, but deference. The "love letters," the summits, the theatrical respect — all of it has been aimed at exactly this payoff. In exchange for saying nice things and staying quiet, Kim has now extracted a concrete strategic concession — a diluted U.S.-South Korea alliance — while giving up nothing: no cap on his weapons, no end to his tests, no change in his declared status as a permanent nuclear power. He flattered, and he was rewarded.

The message lands well beyond Seoul. Watching an American president downgrade a treaty commitment because a dictator complimented him, U.S. allies across the region were left nervous — recalculating how much they can rely on a security guarantee that now appears to bend to whoever strokes the president's ego. That is precisely the doubt adversaries spend decades trying to create among America's friends, and Trump manufactured it himself, in a single social-media post, for free. Kim, as Trump says, understands him. That is the problem.
