Having a right to opine from having been there and done that, I must say that I don't seriously disagree and it is worth considering: Stanley McChrystal says the U.S. should reinstitute the draft

From The Washington Post:

“America suffers right now from the fact that many Americans don’t meet or deal with anybody outside their social or cultural circle,” retired Gen. Stanley McChrystal tells Foreign Affairs in a lengthy interview. “I think mandatory national service would have a huge effect to help us in that direction.”

It’s not a fundamentally new argument to say that the U.S., if it had a draft military, might be more careful about using military force and more restrained in deploying its service members. Still, it’s interesting to see McChrystal, who led the international force in Afghanistan before resigning in disgrace in 2010, making that case himself.

The “reinstate the draft” argument is typically associated with liberal Democrats and with opponents of U.S. military action, not with the generals who lead that action.
