The US should not have created the UN if it does not want to play by the UN's rule. Russia (when it was the USSR) never wanted a UN. Russia is not saying no to Bush's Iraq agenda, just that they want a say in it, as is their right as a security council member.
PS: I want out of the UN. While a member I feel honor bound to follow its rules, but I don't like their rules, so I want out.
Unlike what Clinton would do, Bush an honorable man, is playing by the UN rules as he is duty bound to by treaty approved by the senate when they approved of the US memebership to the UN.
