As the US walks away from the Iran deal is Washington headed down the road to war? That's the assumption of the deal's supporters, the main talking point – but is it necessarily true?

President Trump's decision, made despite pleas from our European allies and even some of his own base, supposedly unmasks him as a dangerous warmonger whose anti-interventionist rhetoric was all a con job. #TheResistance is deeply invested in the idea of Trump as an orange-tinted version of Attila the Hun, whose bombastic personal style reflects a tendency to bomb first and talk later – and now, at last, Trump is showing his true colors. That's the party line.
