Donald Trump has saved the liberal international order—and with it the promise of American global leadership. The bombing of Iran’s regime is the latest sign that a revived order will reassert the fundamental principles of muscular liberalism that defined the post-World War II era. Critics have spent the last decade bewailing Trumpism as a threat to the post-war order. By now, however, it should be plain that they were wrong. The Trump Administration has rebuilt a system of effective deterrence against threats to international peace and security, and a grateful world will someday recognize his achievement.
Unlike Britain, our imperial tradition was born before, not after, our rise to national greatness. That means we never suffered the sclerosis of bureaucratic management in foreign affairs that eventually defeated the British Empire. George Washington helped himself to war-torn Indian lands after the Seven Years’ War. Andrew Jackson violated Spanish sovereignty to march on Florida during the War of 1812 because of Spain’s inability to control Indian and British abuses. John C. Frémont was a key actor when Mexican rule collapsed in California.
Our imperial tradition culminated in the construction of the liberal international order (LIO) after World War II, which was a substantive order, not a procedural one. The aim was to ensure peace and security, and to advance free and democratic societies. Whatever rules and procedures accrued from that order were subordinate to its substantive aims.
