Iran is due for 'elections' in June, which I think will have some impact on the bellicosity of the region.

Personally, I think there is LESS danger of a nuclear exchange between Iran and Israel than of a lot of other things happening. Nations do not wish to be targets, so nations limit their vulnerability. Ahmadirtyjob is a nasty piece of work, but he is not insane.

Ethnically, Persians are distinct from Arabs. I've heard some Mideast experts opine on the perception of danger from Iran being comparable in Saudi Arabia as with Israel. Saudi Arabia is populated by Wahhabi Sunni Arabs and in many cases may have less commonality with Iran than, well, Israel.

I would say that WW3 is going on right now, this worldwide, ideology fueled and internet moderated concatenation of nasty behavior. Not to mention a significant American presence in Iraq and a commitment by the current US administration to prosecute military operations in Afghanistan with tie-ins in Pakistan.

The only issue I'd take with Carol's false flag comment is that it isolates Israel for some reason while in fact it applies to pretty much every actor in the Middle East, Europe, North and South America, Al Qaida, El Segundo, and the Midwest (I'm thinking about YOU, OHIO! I know those designs you have on Kentucky!)
