What we know about how great power wars start should make us terrified of President Trump.
I don’t sleep at night, because of Donald Trump. This is unusual. I wasn’t kept awake at night by George W. Bush or Bill Clinton. Nor do I lose sleep over hot-blooded authoritarians such as Vladimir Putin, Kim Jong Un or Turkey’s Erdogan.

Why? The reason I’m being kept awake – for the first time in my life – by, and am terrified of, a democratically elected politician is simple: given that wars between superpowers are often caused by unpredictability and miscalculation, the danger of nuclear war will most likely increase significantly under President Trump.
At this point many, perhaps particularly on the left, will object that Hillary Clinton would have posed a greater threat to world peace than Trump. She would have taken a hard line with Russia; probably boosted NATO forces in Europe; imposed a no-fly zone over Syria; and been hawkish in the Middle East. As Trump’s election campaign, Russian propagandists, and far left-wing critics of Clinton were prone to claim, Clinton’s foreign policy would have started World War III. Nonetheless, I wouldn’t have lost much sleep over a President Hillary Clinton, but Trump’s presidency scares me to death.
