they had been ready with the mantra that the LeT (and all other terrorists including the ones in j&k) are just misguided boys whom a little tender loving care would fix.
now that the same cuddly terrorists are shooting at yanks, they are evil as heck. amazing what clarity your neck being on the line brings!
they just 'discovered' that the LeT are terrorists! much like they discovered late in the game that the erstwhile 'our man in the middle east' saddam hussein was not quite the doll they claimed he was.
