The least bad exit from Trump's war of choice

The deal announced by the US and Iran after weeks of diplomatic back and forth holds out hopes of an end to a conflict that has engulfed the Middle East, and a reopening of the Strait of Hormuz. It is, though, still far from being a permanent settlement. It extends an April 8 ceasefire by 60 days during which many of the thornier issues, including the fate of Iran's nuclear programme, will be tackled. Spoilers are possible, and the region will remain on edge. Both parties will use the days before Friday's scheduled signing to spin their versions of the deal. But it is a welcome step that should at least put a lid on Donald Trump's reckless war of choice.
