Right. And did the UN forbid any preventative wars?
I mean, the coalition forces freed the Iraqi people, that's really great. Saddam's deeds and his cruelty might justify such a war. But the other reasons accounting for a war fought by the US do not seem to apply. I mean, if this war was really thought in order to secure national security of the US this was an preventative war and that is not jstified, it's even worse. Thus the US is in the same situation the Iraq was in: Disobeying UN decisions. What I am trying to say is that the many reasons the US used as accountance for a war are mostly senseless and some even worse. The only, really applying reason is the intention to establish a freed Iraq. This is - in my eyes - justified, I mean, we did so in Kosovo and other countries as well.
However, this does not really justify the means. Cluster bombs are certainly not that perfect weapons for freeing a state.
