We should STAY OUT OF IT.
Let the Saudis march in to protect their Arab brothers and let Iran and the Saudis and other Arabs annihilate each other.
None of them is good for us.
I think one of the reasons they put the army closer to Israel is because we are moving in position to move agressively against Syria.
The message is clear. If the US acts in Syria, the Syrians will attack Israel. -And the Iranians want to help.
