The news from Afghanistan is very bad. No one says that, of course. President Ghani has a “national unity government” that “supports a strong partnership with the United States”, according to Barack Obama two months ago. Sure, Kunduz was captured by the Taliban – but then the Afghans got it back (though minus one American-bombed hospital, along with most of its patients and doctors). Sure, Sangin was captured by the Taliban – but now the Afghan army is fighting to get it back. But didn’t more than a hundred British soldiers die to hold Sangin? Sure, but American troops in Iraq died to hold and keep Mosul – and Mosul is now the home of the Isis leader, Abu Bakr al-Baghdadi. And US troops in Iraq died to capture Fallujah, then lost it, and died all over again to recapture it – and Fallujah is now in the hands of Isis.
