Hi dig,
Agreed. That's more-or-less my reasoning.
I don't really care what side he takes at this stage. Just stand for something. It's okay to get your hands dirty once in a while.
Sitting on one's hands and waiting to swoop in on the side of the winner while a civil war is in formation is exactly what he did in Syria.
If the US chooses a side, perhaps it can help avert a civil war.
And if it chooses the MB, but makes it a condition of its support that there should be a new election, maybe it will stop them aligning with AQ.
