America is hardly unpredictable. No Trump fan I, but McCain, Clinton, Trump, Trudeau and others are all down with this attack. Predictably enough. Chemical weapons use gets a response. Obama would have attacked too but was trying to enlist Russia in a co-operative action, didn't work but it was smart to try.  America will attack when chemical weapons are used. Foreign observers knew that both Clinton and Trump were hawks (no one believed Trump's garbage for a second that he was anti-intervention because he had long been established as a next-level liar). Everything is so predictable here it's banal.
