The London Ambulances Attack: Of Course It Was A False Flag

The notion that the Iranian state would discredit itself by choosing to attack an ambulance service in London is crazy. Iran has not even attacked any hospitals or ambulances in Israel. Iran has absolutely zero record of attacks on healthcare facilities. That is of course in stark contrast to Israel which specifically targets them in Gaza and Lebanon. The obvious revulsion of a UK public, that has been opposed to the war on Iran, at the destruction of the ambulances would far outweigh any possible gain. What precisely is the gain that Iran is supposed to have sought?
