>>When in doubt, blame the US, eh? If I recall, it wasn't us that blew up the mosque. It isn't us that wants a civil war there. Try blaming another country. I'll give you a clue. Four letters, starts with "I", ends with "n".

>I've heard that the border with Iran is one of Iraq's most secure since Iran doesn't want a spill over of insurgents. The Shia in Iraq, though sharing a sect of Islam with Iran are highly suspicious of them. I think it was on Charlie Rose... there was some intelligence specialist that said that Iran has the power to serious derail the situation in Iraq if it wanted to participate in the insurgency. I will try to find a reference.

That Iran doesn't want insurgents coming into the country (Iran) doesn't mean that they don't also send people/money/munitions INTO Iraq.
