the cold war was mainly a stand off, or fought between allies of the superpowers. eg;vietnam, afganistan, iran-iraq etc..America has just essentially dictated international law,so how does it weaken america. i just think that if America has the ability to attack its enemys for future potential threats, then so does every other country. And thats a big horrible mess for us all to live in. i am pretty guilible i guess and i live in ireland, not really a prime target in any war,my nations harmlessness is my curtain of security. but to extend the idea of preemptive action to all states as you must logically do, then its just a free for all, and nobody wants that
