Who IS funding the Sunnis?

And why hasn't this question been asked of the Saudis?

Cenk Uygur of Huffington Post:

To hype up Iran's involvement in the forces fighting against us in Iraq when all available intelligence indicates that we are fighting the Sunnis instead is unconscionable and inexplicable - unless, of course the explanation is that you don't care about the troops, you just want to manufacture a reason to attack Iran.

In his press conference on Wednesday when asked why the administration is making claims they couldn't back up against the Iranian government, President Bush said, "Does this mean you're trying to have a pretext for war? No. It means I'm trying to protect our troops."

Really? Then tell us who is providing the money for the weapons that kill the great majority of them. Tell us who's funding the Sunnis.
