I re-read my post, domer, because I take complaints and criticism from you seriously, and the only possibly offensive line I could find was the one beginning with "You got a lot to learn . . . " which obviously is patronizing but not something that I wouldn't say in an argument with someone I respected as a person, if I felt he or she was displaying a lot of naivete. However, I believe I inadvertently offended you with that, and if I did, then I apologize.
Looking at your questions (all of which are unanswered and IMHO unanswerable) they seem to run the gamut of post-withdrawal "bad outcomes" - - "stepped-up" civil war with genocide, "stepped-up" civil war without genocide, stepped up civil war with French fries, failed state with terrorist enclaves, failed state without terrorist enclaves, etc. Not mentioned were the less dire outcomes, such as, Iraqi factions, finally convinced that America will not help them prevail over their domestic enemies, forced to come to grips with their differences and hammer out a political settlement despite themselves, not a totally unrealistic expectation and certainly no more or no less predictable than any of the other "disaster" predictions made.
I think you nailed it with your "the Hamlet of East Orange" line. Since no one can predict any of the outcomes with any reasonable degree of certainty, your endless agonizing over what'll happen after a pull-out is pointless and counter-productive. Since the present situation is, in the eyes of the NYT (and IMHO in the eyes of those whom the NYT has identified correctly or not as the real decision-makers in American foreign affairs and quite possibly for whom they speak) untenable regardless of the possibility of genocide, it must be terminated. Meaning that whatever the outcome, it (the outcome) will have to be dealt with tomorrow and not today. Another excellent illustration of that magnificent Biblical line, "Sufficient unto the day is the evil thereof."
