Donald Trump, by contrast, has rarely exhibited forbearance in any context. The chances of a conflict occurring on his watch are also considerable. They would be for any president--the United States fought land wars or suffered major terrorist attacks under six of its last twelve elected presidents. But given President Trump's foreign policy ineptitude, the risks are especially high. We fear that if Trump were to confront a war or terrorist attack, he would exploit this crisis fully--using it to attack political opponents and restrict freedoms Americans take for granted. In our view, this scenario represents the greatest danger facing American democracy today.
