The PRESidENT has already told us many times what he considers victory: complete withdrawal of all US forces. He is a rabid anti-colonialist and categorically rejects any notion of American exceptionalism or moral imperative.
No big mystery there.
Right. Obama does not want to win but he is too gutless to simply come home. The vacillation has caused more USA deaths than under all 8 years of Bush. (Seriously). Obama is a coward but he does not mind our boys and girls shedding their blood over there just so he is not correctly accused of being a craven wimp.
