This has always been my opinion: by definition the UN can't really have enforcement power...but a huge problem in international politics is that you have to actually have protocols and procedures by which the various world powers can communicate with each other at the correct levels of government. It's the physical action problem: when a government makes policy, how does that go from words to actions? In the international relations business it's the same issue: the prime minister or president or whoever wants to communicate a message reliably to other nations - but who exactly do they talk to do it? (this problem was why the hotline system between the US and Russia was setup after the Cuban missile crisis - a major issue driving the decision making was 6 to 12 hour communication delays trying to go through embassies and hoping messages were being accurately sent).
