On Tuesday, Donald Trump’s head of counter-terrorism strategy, Joe Kent, quit in protest at the ongoing war on Iran. Kent is a luminary of the US far right, a conspiracy theorist with ties to white supremacists and neo-Nazis. His resignation letter suggested that Trump had been tricked into war by Israel and – telling phrase – “its powerful American lobby”. What’s more, he said that this was “the same tactic the Israelis used to draw us into the disastrous Iraq war”. That last line was the giveaway. It’s long been a staple of antisemitic orthodoxy, though easily debunked: in fact, Israel counselled against the invasion of Iraq, fearing that it would strengthen Iran.
