re: UN
It's quite easy to put the blame on the UN, isn't it?
First, about the Iraq issue, the UN was right: no WMDs!
Second, the UN's role (security council) is to prevent wars, not to interfere with internal matters inside sovereign states.
Third, there's the HRC, but it can't enforce anything, it can only report.
Fourth, the various competences of UN institutions depend on the UN members.
There are many more institutions than when the UN was created.
One of them is the ICC.
