Yes, Iran has been a responsible "regional power" so far hasn't it? I wonder how many US soldiers and Iraqi civilians have been killed by Iranian agents or the weapons they've supplied to Iraq?

Most of the American dead have been at the hands of Sunni insurgents, and their support mainly comes from Saudis and Jordanians. The Iranians have an interest in importing arms into Iraq, but not to use against Americans. Why should they want to fight the Americans when they're doing such a good job of suppressing the Sunnis for them? There might be some Iraqi nationalists like Sadr who resist both American and Iranian influence in Iraq, but in the main, Iranian interests lie in letting the Americans fight for as long and as hard as possible on their behalf. The Iranian agents you should be worried about are those in the Iraqi government who constantly plead for you to stay and safeguard their "democracy". The day you wise up will be the day their "democracy" is secure and American soldiers are welcome no more. The Iranian weapons are being stockpiled for that day, for use against Sunnis.
