Obama already gave the Taliban what they wanted with his speech at West Point, i.e., complete withdrawal by a date certain, 2016. Letting these Taliban return to Afghanistan must send shivers down the spines of the recently elected Afghan government.
I’m sure “Mr. Petty” Obama is so ticked off at Karzai for not signing the extension of forces and US troops immunity agreement that he just had to leave that little pin-pulled grenade on his doorstep (just to show him).
