Iran Pulling Insugent Strings in Iraq

The UK Guardian reports that Iran has increased the number and scope of attacks from insurgent groups they control and influence in Iraq.  Their aim is to play into the discontent of the Democrats in Congress to force an American withdrawal by September:

Iran is secretly forging ties with al-Qaida elements and Sunni Arab militias in Iraq in preparation for a summer showdown with coalition forces intended to tip a wavering US Congress into voting for full military withdrawal, US officials say.

"Iran is fighting a proxy war in Iraq and it's a very dangerous course for them to be following. They are already committing daily acts of war against US and British forces," a senior US official in Baghdad warned. "They [Iran] are behind a lot of high-profile attacks meant to undermine US will and British will, such as the rocket attacks on Basra palace and the Green Zone [in Baghdad]. The attacks are directed by the Revolutionary Guard who are connected right to the top [of the Iranian government]."

The official said US commanders were bracing for a nationwide, Iranian-orchestrated summer offensive, linking al-Qaida and Sunni insurgents to Tehran's Shia militia allies, that Iran hoped would trigger a political mutiny in Washington and a US retreat. "We expect that al-Qaida and Iran will both attempt to increase the propaganda and increase the violence prior to Petraeus's report in September [when the US commander General David Petraeus will report to Congress on President George Bush's controversial, six-month security "surge" of 30,000 troop reinforcements]," the official said.

"Certainly it [the violence] is going to pick up from their side. There is significant latent capability in Iraq, especially Iranian-sponsored capability. They can turn it up whenever they want. You can see that from the pre-positioning that's been going on and the huge stockpiles of Iranian weapons that we've turned up in the last couple of months. The relationships between Iran and groups like al-Qaida are very fluid," the official said.
