The social impossibility of a war with Iran has been more or less constant for decades. I don't know how bad I feel for any Iranian military getting caught in Iraq. Maybe stay in Iran. Your uncles died as child soldiers proving that border is there.
Trust me buddy, if it was all up to me we'd have never been there in the first place. Let NATO jump in on Saddam during the Arab Spring if they're so keen on it, same outcome but at least it looks international-ish and we can keep our name off it and our boys out of it
