What will Trump do about the 'Animal Assad'?

Donald Trump’s response to the alleged chemical attack in Syria which left dozens dead has so far been entirely typical: he has sent a series of angry tweets. But now that the president has finished typing will he go one further and press any red buttons? More than a day on since the bombing, the United States has held back on retaliating, leaving another western ally – believed to be Israel – to target the Syrian military airport from which it is thought the attack was launched. Trump has certainly piled pressure on himself to act, and there are several reasons to think military action will be imminent. Firstly, the president didn’t hold back on pinning the blame on ‘animal Assad’, even if, officially, the US is still waiting to see who was actually responsible. In his tweets, Trump also promised a ‘big price…’. For a man of his ego, this would make it more surprising than not if he backed down and didn’t act against the Syrian regime.
