No, no, a thousand times No. Don't give into these neocon proposals. We are a sovereign nation, and all we need to do is simply reclaim our sovereignty. A "Democratic Alliance" would be even more powerful than the current UN, and would sap our sovereignty that much further. Don't go there.
Agreeed!!!!
If we were to try to realign the UN to give vetos to the countries that truely deserve them (such as China and India) there is a good chance the rest of the world would vote us off the Security Council.
