Nicholas Kristof: Donald the Dangerous

Is there any scarier nightmare than President Donald J. Trump in a tense international crisis, indignant and impatient, with his sweaty finger on the nuclear trigger? A starting point is Trump’s remarkable ignorance about international affairs. And every time he tries to reassure, he digs the hole deeper. Trump has also called for more U.S. troops on the ground in Iraq, and raised the prospect of bombing North Korean nuclear sites. A poorly informed, impatient and pugnacious leader can cause devastation, and that’s true of either Kim Jong-un or Donald Trump.
