Does he?
This strikes me (so to speak) as a dangerously impetuous piece of Twittoric, with its questionable targeting of cultural sites and the childish “52 sites for 52 hostages thing.
The tragedy is that I’ve no doubt the US is on the “right side” here but contrast this rant with the Iranian counter-tweet with its talk of “peremptory norms”
(Jus cogens)
Ask Trump or indeed anyone else what all that is about and you’ll probably get a long silence.
So Iran, albeit hypocritically, looks like the reasonable side here while Trump no doubt has many of his own people slapping their foreheads in despair.
