Well i think the excuse was going to war was very poor as it is. The americans failed and are now trying to cover up their mistakes. You really think they care about people's liberty? I don't think they're going to be going anywhere near zimbabwe or Libya even though they have dictatorships. It's all for the oil; that's all they're interested and being the only superpower.
Iraq is in a right state at the moment, there is no order. There is no government, the Poilice are not even trained. The only order there is in Iraq is guns.
