"Do you think the UN will survive without the superpowers having their veto right " No. "Do you think that it is about time that the veto power is taken away from the permanent members and it is replaced with something more practical like a super majority of say 66% or 75% or any other ratio of members. " Sure, once the US pulls out of the UN.

Why would any SuperPower surrender its power to the U.N. ? The veto is a requirement to even get the SuperPowers to participate. It may seem unfair, but look around you anywhere. Parties with more power don't want to give up their power to parties with lesser power, no matter how unfair it may seem. Even if the U.N. wasn't riddled with corruption, and composed of a large majority of governments with their own corrupt interests, it still wouldn't be a good idea. If the minor powers of the world are unhappy with the U.N., they should form their own international organization (as some have) and see how successful it will be. Maybe they can recruit some idealistic young Americans to help them administer it.
