(this is no US bashing almost every nation in the security concil is in debt (germany for instance has choosen to split their payment, so we pay twice a year instead of a big amout of money once a year, of course we didn't asked the UN if this is OK))
Personally I would disband the council, the veto power often is used for strange political games (USA will veto any russian/chinese resolution and vice visa).
Plus, mainly for the same reasons, I would like to see a mobile and quick "UN Response force" so the UN is autonomous from the mood swings of its members. This army would be under the command of the UN and not longer of their home-nations.
