The UN is seen to have its future in the balance. Will it fracture from conflict and the US, backed by its coalition of the willing take the policing of the world of nations into their own hands?

Thats what the neo-cons want because they see the UN as a total failure in terms of enforcing global peace and security. The US is best off doing the job itself. They have no time for Kofi Annan view of the UN as providing a common framework for securing peace.

There is another way of looking at the UN. The West has long used the UN along with other international institutions (IMF & World Bank) as an instrument to run the world to maintain Western predominance, protect western interests and promote western political and economic values.

I reckon thats how it would look from the perspective of the Arab states.
