I don’t see it on the horizon and as long as Kerry and Obama keep mincing words and parsing the truth they spoon feed the American public, it’s arguable they’ll never be believable.
As Obama, Kerry, McCain and Graham walk around trying to convince the American public that Bashar al-Assad is not only a meanie and a bad, bad man for having gassed his own people if not outright killing them, it’s been noticed nobody is even broaching the possibility the Sarin Gas might have been used by Al Qaeda.
