In a further fracturing of the very shaky ceasefire between Iran and the United States, the Iranian Revolutionary Guard Corps (IRGC) this week shot down a US Army Apache attack helicopter near the Strait of Hormuz.
At any other time, the US would have seen this as an unacceptable act of war requiring a very strong reaction. But where Donald Trump’s unpredictable social media output would usually have breathed hellfire and damnation, this time it talked a proportionate response.
It seemed a welcome sign that Trump’s advisers, and maybe even the president himself, are having to accept that this war will not be won by bombs, missiles and drones, and will have to end in compromise.
