Where do you find support for the idea that "training the Iraqi army" is a feat still within our grasp?
Who'd's response actually brings to light one of the more serious problems affecting us as Americans.
Contrary to some of the accusations levelled by the more serious, libelous warmongers, Americans feel at home travelling anywhere in this country and have no trouble understanding that our loyalty and the "providing for the common defense" that we all share operates on a national level. I can fly to Birmingham, Alabama one day and Chicago, Illinois the next and while I might feel uncomfortable getting into serious political debates in barrooms in those places, I can reasonably expect to come away from such a conversation alive.
In Afghanistan and Iraq, however such confidence is totally misplaced. Tribal/Religious identity trumps nationalism and we as Americans just don't get it.
That's why Who'd and others who think similarly think that "a sovereign Iraq able to truly act like one, including quelling sectarian violence, and resisting the influence of Iran is actually achievable. Nothing in their immediate experience suggests otherwise.
That's why I pray vigorously that at some point in our near future, we can put adults in charge of our foreign policy and give the frat-boys a well deserved time-out.
