SecState John Kerry said at today's congressional hearing that Arab counties have offered to pay for regime change in Syria:
With respect to Arab countries offering to bear costs and to assess, the answer is profoundly yes. They have. That offer is on the table.
In fact, some of them have said that if the United States is prepared to go do the whole thing the way we’ve done it previously in other places, they’ll carry that cost.
That’s how dedicated they are at this. That’s not in the cards, and nobody’s talking about it, but they’re talking in serious ways about getting this done.
