TO DONALD TRUMP, the current world order is a criminally bad deal for America. He is ready to play good cop and bad cop to fix this. Public enemy number one is China’s economic model, which he has called a conspiracy to steal wealth and manufacturing jobs from America. But allies are prime suspects, too, accused of cheating America in trade while doing too little for America’s national security. Allies from Europe to North America and Asia can expect to meet both the smiling and snarling versions of President Trump, all too soon.
