Many veterans are understandably bewildered and angry and wondering if their sacrifices were worth it. Some even suggest that the dismal outcome in Iraq and to a lesser extent Afghanistan is an indictment of the armed forces that fought there. This is a point that retired Lt. Gen. Daniel Bolger, who served in both Iraq and Afghanistan, makes in this New York Times op-ed, which previews a book he has written. He argues that the “surge” in Iraq never really worked, that it was only a short-term palliative, and then issues a withering indictment of the U.S. Armed Forces:

We did not understand the enemy, a guerrilla network embedded in a quarrelsome, suspicious civilian population. We didn’t understand our own forces, which are built for rapid, decisive conventional operations, not lingering, ill-defined counterinsurgencies. We’re made for Desert Storm, not Vietnam. As a general, I got it wrong. Like my peers, I argued to stay the course, to persist and persist, to “clear/hold/build” even as the “hold” stage stretched for months, and then years, with decades beckoning. We backed ourselves season by season into a long-term counterinsurgency in Iraq, then compounded it by doing likewise in Afghanistan. The American people had never signed up for that.

Self-criticism is always welcome and certainly to be preferred to generals who claim they never got anything wrong. But this self-criticism, I would argue, is excessive. It’s true that the U.S. military was not well prepared for the counterinsurgencies it encountered in Iraq and Afghanistan and that it went into those wars optimized for another Desert Storm. The U.S. military made countless blunders in Iraq between 2003 and 2006 which exacerbated the situation. But it’s also true that the U.S. military is a learning organization that improvised brilliantly under fire. Thanks to the acumen primarily of NCOs and junior officers–gradually followed by more senior officers–the U.S. military by now has become one of the most capable counterinsurgency forces in history.

And contrary to General Bolger’s assertions, the “surge” (which I’m told he opposed while working at Central Command for Adm. Fox Fallon) did work–it reduced violence by more than 90 percent. By 2009 both AQI and the Shiite militias such as the Mahdist Army had been decimated and Iraq was on the road to stability. No less than Vice President Biden publicly bragged in 2010 that a “stable” Iraq would be “one of the great achievements of this administration.” Then of course this administration pulled all U.S. troops out of Iraq, while doing nothing to stabilize Syria in the throes of its civil war. The result has been the rise of ISIS and the undoing of what U.S. troops fought to achieve.

That is demoralizing, to be sure, but Bolger is wrong to blame the military for this outcome. I agree with Bolger that the military can’t dodge blame for the disaster in Vietnam because Gen. William Westmoreland’s firepower-intensive approach did not defeat the Viet Cong and did exhaust American will. The U.S. military was on the verge of repeating the same mistake by 2006 but the surge really did rescue the operation even if it didn’t produce nirvana or magically solve all of Iraq’s underlying issues. No one–not even the most wild-eyed surge proponent–ever expected that it would.

There was always a widespread expectation among surge proponents that U.S. troops would have to stay for the long haul to guarantee Iraq’s stability just as they have stayed in Germany, Japan, South Korea, Kosovo, and other places. It is quite possible that if U.S. troops had been pulled out of Europe after 1945 a disaster would have ensued similar to the one that ensued after the removal of U.S. troops in 1919. But that would not have been the fault of Patton, Bradley, Eisenhower, and the other generals who won the war. Likewise it is not the fault of soldiers today that President Obama didn’t stay the course in Iraq and now threatens to also prematurely pull out of Afghanistan...
