We can use them as target practice................
Iraq was a military powerhouse compared to Iran. Iran has been suffering under sanctions for too long. Being a religious state, they are prone to removing military people who don’t toe the line. Their soldiers are better than Saddam’s but their equipment is complete shiite. Their best stuff is anti-ship missiles and S-400’s. They can hurt us with both.
Six B-52’s carrying cruise missiles can reduce them to cave-dwellers. They’ll be limited to launching SCUD’s at Saudi Arabia and Israel. But invading them will be tricky if not impossible.
