John Kerry actually said...

"We could, for example, tell Assad that the use of barrel bombs must end--and that if they continue, we will stop the Syrian air force from flying."

"I am quite concerned that if the United States walks away from this current agreement, as imperfect as it may be, that the rest of the world will blame us for doing so, not the Iranians."

"Russia's actions to bolster Assad increase the imperative of support for the moderate opposition and Syrian civilians."

"What we do will have to pass muster with Congress. We well understand that."
