Oh, brilliant idea.
For your information, the bulk of the Iraqi Army -- including almost the entirety of combat ready units -- is composed of members of the Badr Organization, the Iranian based Shi'ite militia.
Many Badr members spent years in exile in Iran, were schooled in Iran, trained in Iran, are now armed, paid and equipped by Iran, and their loyalties are about as clear as anything can be.
Moreover, Iraq's own Defense Minister claims that the Iraqi Army won't be able to defend Iraqi borders (let alone project power) for at least THIRTY years.
What does that mean? Even if, by some miraculous feat, you somehow managed to persuade the Iraqi Army and the elected government to side with America against Iran (practically an impossibility at this point), they'd have approximately the force projection capabilities of the security force at the San Diego Zoo.
I think you need a new plan.
A lot of the military discussion here is on about an 8th-grader level and largely consists of the coolness of stuff gettin’ blowed up. (Not that I don’t like stuff blowing up as much as the next guy, and fortunately, I get paid to watch stuff blowing up at times.)
People need to go back to playing “Risk.”
