Tick, tock, tick, tock ...
Frankly, This is all about Iran.
The younger generation there want to throw off the tyrany of mulla rule. The only thing preventing them from taking control is the threat of the countries to their east and west. US troops are in Afghanistan, and US troops are in and around Iraq. The students could do their thing with absolutly NO threat from either country.
If the Iranian students ever were waiting for a good time, that time is now !
