QUOTE : That raises the most serious threat to the liberal international order—which is not China’s expansionism but America’s abdication. The architect of this system is rapidly losing interest in its own creation. As the scholar Walter Russell Mead has pointed out, Trump’s instincts are Jacksonian, in that he is largely uninterested in the world except insofar as he believes that most countries are always swindling the United States, including and especially its allies. Trump is a nationalist, a protectionist, and a populist, determined to put “America first.” But truthfully, more than anything else, he is an isolationist who has abandoned the field. Trump has withdrawn the United States from more organizations, treaties, and accords than any president in American history. Not only has he slow-rolled a trade deal with the European Union but he has also started a trade war against the bloc and moved to pull troops from European bases—seemingly heralding the end of a seventy-year Atlantic partnership.
