To be truthful, the best strategy going out would be for him to kill Assad going out, then the next President can say they were not in on that.
I'm not sure why Assad should be taken out. All he's been doing is defending his country and his people from murderous terrorists bent destroying a once peaceful, westernized, religiously tolerant Middle Eastern country. And those terrorists and their "spontaneous" uprising through "peaceful" protests have been funded, armed and supported by Obama and the CIA.
To attack Assad we have to attack Russian SAMe and airplanes. This is a call to start WW3.
