Time after time, West shows the theory of counterinsurgency scraping up against the hard and jagged ground of the real Afghanistan. In one instance, he examines the work of a group of American soldiers and civilians, known as a provincial reconstruction team, whose job was to provide development assistance to Afghan locals in Asadabad (A-Bad to the Americans) in eastern Afghanistan. It was overseen by a battalion known as the 1-32 and commanded by a lieutenant colonel named Mark O’Donnell. In June 2009, after the reconstruction team had been working there for three years, an American supply truck blew a tire on the main road. A crowd of Afghans gathered, and then suddenly a grenade exploded, killing and maiming several Afghans. A riot ensued. “Kill the Americans!” the Afghans shouted. “Protect Islam!” Only later did a videotape of the incident show clearly that an Afghan had tossed the grenade.

About this, West writes:

“For three years, the provincial reconstruction team had lived in a compound a few blocks from the scene of the tragedy. The P.R.T. had paid over $10 million to hire locals, who smiled in appreciation. Every time a platoon from 1-32 patrolled through town, they stopped to chat with storekeepers and to buy trinkets and candy to give to the street urchins. Yet the locals had turned on the soldiers in an instant. That the townspeople in A-Bad who profited from American protection and projects would believe the worst of O’Donnell’s soldiers — whom they knew personally — suggested that the Americans were tolerated but not supported, regardless of their good works and money.”

West’s book is coming out just as the American military, fortified by the extra troops, is claiming to be making significant progress in routing the Taliban from their strongholds in the south. This may be true, but remember who is doing most of the hard work: the Americans, not the Afghans themselves. It’s still an American war.

The subtitle of West’s book promises a “way out,” but it’s a little thin on exit strategies. His solution, tacked on to the final pages of the book, is to transform the American mission to one almost entirely dedicated to training and advising the Afghan security forces. Let the Afghans fight. “Our mistake in Afghanistan was to do the work of others for 10 years, expecting reciprocity across a cultural and religious divide.”

West is not the first to advocate such a course. But it’s not that simple, as he well knows. Nothing in Afghanistan is. Nine years of training and investment have created an Afghan Army fraught with the same corruption and lack of cohesion as the rest of the country. As it is, the Americans are now pouring more resources into the Afghan security forces than ever before. At best, the Afghans are years away from taking over the bulk of the fighting. And even that is a very fragile hope.

Until then, what? As “The Wrong War” shows so well, the Americans will spend more money and more lives trying to transform Afghanistan, and their soldiers will sacrifice themselves trying to succeed. But nothing short of a miracle will give them much in return.
