Assad was the Iranian ally and almost like a satellite state and with the fighting in Syria and the almost certain eventual toppling of Assad Iran can no longer rely on Syria so they are looking for a new arab friend. The smart thing would also be for Iran to stay out of being involved in Syria openly because if they are not seen as interfering then they can try get on good terms with a post Assad government so even if they loose Assad they do not loose Syria.

I had to crack up. WHAT? Did Iran offer Sudan help? How and with what? Attacking Israel? Iran's air defenses? Hee hee hee. This is so funny. Perhaps they should have and that will be very sobering to those who still do not know Israel's resolve.
