British fear Petraeus is beating the drum for Iran strikes

"Petraeus is going to go very hard on Iran as the source of attacks on the American effort in Iraq," a British official said. "Iran is waging a war in Iraq. The idea that America can't fight a war on two fronts is wrong, there can be airstrikes and other moves," he said.

"Petraeus has put emphasis on America having to fight the battle on behalf of Iraq. In his report he can frame it in terms of our soldiers killed and diplomats dead in attacks on the Green Zone."
