The Bush administration claims that they care so much about protecting our troops in Iraq that they are going to go after Iran, who is at most responsible for 8% of US fatalities. Then, why not go after the people funding the Sunnis instead? After all, they are the ones doing the great majority of attacks against our beloved troops.
Yesterday, I concluded that the reason might be because some of that funding goes back to the even more beloved Saudi government. I came to that conclusion based on what analysts, experts and reporters in the field say and what the Iraq Study Group concluded, but I suppose I could be wrong. So, if this administration cares so much for the troops dying in Iraq, as they claim, why don't they investigate who is sending the money for the weapons that are killing over 90% of them?
If they don't do this, then it becomes patently obvious that they are using the troops as an excuse once again for their real agenda. They want to attack Iran at all costs.

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.
