EU sanctioning one non-EU country for trading with another non-EU country. Spain not prepared to pirate Iran's ship so the Yanks gave London a bell knowing it'll comply with being a useful idiot. Iran retaliates, as it had to, Britain stamps its feet like a chastened 10-year-old. Johnson may be daft enough to do a Jimmy Carter by sending in the SAS or SBS to try and liberate a vessel that has no British crew.
