He wants to seize the Panama Canal, Canada and Greenland. And now wants to rename the Gulf of Mexico the Gulf of America

Donald Trump’s silly season has already caused irreparable damage to United States national security. Despite not yet holding office for a minute, Trump has made it plain that in his second term the U.S. will be an unreliable partner swayed by his personal whim, that he has no respect for historic alliances and that he has contempt for the rule-based international order that the U.S. has led since the end of World War II to prevent the reemergence of catastrophic great power collisions.

Beginning with his “Merry Christmas to all” tweet that he wanted to seize the Panama Canal, Canada and Greenland, Trump has not relented in his absurd claims, extended to renaming the Gulf of Mexico the Gulf of America. His disdain for the sovereignty of independent nations—two of them NATO allies and Panama a fellow member of the Organization of American States—has undermined the credibility of opposition to Russia’s invasion of Ukraine and China’s ambition to grab Taiwan. The soft power of the U.S., ultimately based on its democratic example and respect for international order, has been tossed away by Trump’s fantasy Manifest Destiny that is simply the latest wrinkle in his isolationism. Hardly the Rough Rider, if Trump were acting as Putin’s or Xi’s agent he could not have kowtowed more for their benefit.
