The Afghan intervention seemed, at the start, a success story. Moreover, he asks why these Western powers stayed on, at a cost of more than $2 trillion and over 3,500 allied lives lost, plus many more soldiers badly injured, fighting what the British brigadier and others long knew was an unwinnable war. In his new book, Malkasian considers just how it could be that with as many as 140,000 soldiers in 2011 and some of the world’s most sophisticated equipment, the United States and its NATO allies failed to defeat the Taliban. A sprawling history of more than 500 pages, the work stands in stark contrast to Malkasian’s previous book, War Comes to Garmser, which tells the compelling story of one small district in Helmand. Its author, Carter Malkasian, is a historian who has spent considerable time working in Afghanistan, first as a civilian official in Helmand and then as a senior adviser to the U.S.

How the conflict once known as “the good war” (to distinguish it from the war in Iraq) went so wrong is the subject of a new book, The American War in Afghanistan, which claims to be the first comprehensive account of the United States’ longest war. In April, Biden announced that the United States would pull all its remaining troops out of Afghanistan by the 20th anniversary of 9/11, ending what he referred to as “the forever war.” But by now, such a withdrawal was all but a foregone conclusion: the Taliban had proved a stubborn enemy that was not going anywhere and that indeed controlled close to half the country’s territory. President Joe Biden appears to have reached the same conclusion as the British brigadier. Defense Secretary Robert Gates promptly denounced Carleton-Smith to the news media as “defeatist.”

He was the first senior coalition military officer to say so publicly, and the story made the front page of the British Sunday Times.

The war in Afghanistan could not be won militarily, Carleton-Smith told me. In 2008, I interviewed the United Kingdom’s then outgoing military commander in Afghanistan, Brigadier Mark Carleton-Smith, in a dusty firebase in Helmand Province, where international troops had been battling the Taliban on a daily basis for territory that kept slipping away.
