Morse Tan, President Trump’s former ambassador-at-large for global criminal justice, is standing trial in South Korea this week on criminal defamation charges for comments he made while on American soil. The case is not just about one man’s speech. It is about whether an allied nation can drag an American into a foreign courtroom for words said at home — and whether Washington will do anything about it.
Why this trial should alarm every American who cares about free speech
Tan’s prosecution is startling: prosecutors in South Korea say he defamed President Lee Jae Myung by repeating allegations about the president’s youth. Tan says he was speaking from sources and belief, pleaded not guilty, and has argued the Korean courts lack jurisdiction over speech made in the United States. The legal claim sounds shaky, but the effect is clear. An American citizen who spoke in America now faces the risk of imprisonment overseas — the indictment could carry years behind bars. That is not justice. That is intimidation.
Travel ban, missed funeral and a thin U.S. response
After arriving in South Korea as an election monitor, Tan was prevented from leaving the country and barred from attending his grandmother’s funeral. Meanwhile, major U.S. news outlets have been mostly silent. Members of Congress and conservative groups have pushed for action, and the State Department has said it “stands ready” to raise concerns in cases where foreign laws punish Americans for political speech. Yet when it came to Tan specifically, the administration politely declined to intervene publicly. Politeness is not a policy when an ally is weaponizing criminal defamation against an American on account of speech made at home.
This is more than one controversial speaker — it’s a precedent
If South Korea can prosecute an American for comments made in the United States, other governments will take note. Authoritarian regimes already bank on weak responses from liberal democracies. Allowing one friendly government to set this precedent weakens U.S. citizens everywhere. It also exposes an odd double standard: American institutions rush to defend free speech at home while treating prosecutions of Americans abroad as a diplomatic squabble to be handled gently, if at all. That caution risks encouraging more such prosecutions.
Wrap-up: Time for bold diplomacy, not headline avoidance
Washington should stop treating this as a minor kerfuffle and start treating it as a free-speech and consular issue. A strong, public diplomatic protest would make two points: we expect our citizens to be safe from foreign prosecutions for speech made in America, and we will not sit quietly while allies use criminal laws to silence critics. The political class and the press owe Morse Tan more than polite statements and silence — they owe Americans a clear defense of the principle that speech at home should not become a crime abroad. If that concept sounds radical today, then we’ve already lost more than one fight for liberty.
