Gideon Rachman: “Donald Trump has a perverse genius for driving American adversaries to discover new forms of leverage over the US. His trade war with China persuaded Beijing to exploit its domination of rare earths and critical minerals, forcing the US to reduce its tariffs.”“In a similar fashion, Iran has now finally carried through on a longstanding threat and in effect closed the Strait of Hormuz. Tehran, like Beijing, will have been delighted to discover how quickly it can inflict economic pain on the west.”“Iran’s exploitation of its control over the strait means that the Islamic republic can now aspire to do far more than merely survive the US-Israeli assault. It has a real prospect of emerging from the war in a strengthened international position.”
