The US military “is more than capable of retaking ISIS-held areas like Ramadi and Mosul,” Mr. Scharre, the former Ranger, notes.
The problem, he adds, is “then what? For how long would US troops stay? A generation?”
The unraveling within Iraq has not been the result of lack of continuous training, says retired Lt. Gen. David Barno, former commander of US forces in Afghanistan. “I don’t see this as a training problem. It’s primarily a problem of willpower, motivation, and leadership.”
This lack of willpower stems from the sectarian divide within the military, which is supported by Shiite national leadership that has repeatedly marginalized Sunni troops within the Army’s ranks.
And so, if it’s “an Iraqi Army that’s at war with itself, are we the ones to fix it?" asks Mr. Barno, who is now at American University in Washington.
Perhaps, he says, the US is the only honest broker in the region. But there are other nations who could lend a hand as well, including European allies, for example, who are closer to the region, many analysts point out. There’s also Saudi Arabia – a close neighbor that has the world’s third largest defense budget – adds Democratic presidential contender Sen. Bernie Sanders of Vermont.
