I never fail to be amused by the "we have nukes and we aren't afraid to use them " brigade. Having weapons and being prepared to use them doesn't make you a responsible person or goverment.
It does make a dictator like Bush (telling others what they can and cannot do is DICTATING ) feel that because they have weapons that it then gives them the right to bully others.
America needs to police it's own and realise they will never be able to force others to follow thier ideals.
