President Donald Trump has at last rediscovered his core foreign policy beliefs and ordered the withdrawal of U.S. troops from Syria. Right on cue, official Washington had a collective mental breakdown. Neocons committed to war, progressives targeting Trump, and centrists determined to dominate the world unleashed an orgy of shrieking and caterwauling. The horrifying collective scream, a la artist Edvard Munch, continued for days.

Trump's decision should have surprised no one. As a candidate, he shocked the Republican Party establishment by criticizing George W. Bush's disastrous decision to invade Iraq and urging a quick exit from Afghanistan. As president, he inflamed the bipartisan War Party's fears by denouncing America's costly alliances with wealthy industrialized states. And to almost everyone's consternation, he said he wanted U.S. personnel out of Syria. Once the Islamic State was defeated, he explained, Americans should come home.
