And Trump put the threat on steroids by not filling numerous state department vacancies, and throwing threats off the top of his head without consulting anyone who knows what they're doing. China finally stepped in, and asked Trump to stop his threats after both China and Russia agreed to heavy sanctions, and instead of giving things an opportunity to work (new tougher sanctions), he keeps pushing another unhinged despot with a game of chicken. 

Someone needs to gag this guy; this isn't a business deal where tough talk may or may not be appropriate. This time there are hundreds of thousands, possibly millions of lives at stake while as Congress and Senate do NOTHING.

Blame whomever you want. Trump's behavior is dangerous.
