Make no mistake: Donald Trump's foreign policy doctrine marks a radical departure from the bipartisan consensus view held in Washington since the end of the Second World War. While Trump has so far offered few foreign policy details — other than the familiar statements about building a Mexican border wall and imposing extreme tariffs on Chinese trade — a recent interview in the Washington Post shed new light on how The Donald views the world and America's role in it.

What's clear is that the central theme of Trump's foreign policy is isolationism. According to Trump, the United States is spending too many resources shoring up rich allies around the globe. Consequently, America should focus on domestic issues and stop bearing responsibilities for global security, or at least significantly reduce its overseas presence.
