Boots on the ground is the only way to win any conflict but that would have collateral damage as well just not as much as bombing the shit out of everything. If we had gone into Iraq and just left after removing Saddam's regime would we not be viewed as asswipes for leaving the people of Iraq to rebuild themselves? Would Iran have used it as an open door to move in and expand their nation after we left? If we do nothing we are viewed as asswipes by the middle east so we are damned if we do and damned if we don't. If Iran is just left alone from now on how long before they and a missile system large enough to carry a nuclear warhead to the US? Diplomacy does not work on nations who just don't care about their standing in the world which is why it will not work on Iran so what should we do about them and their striving for nuclear weapons?
