You scum, not only are you narrow minded but you are ignoring all the variables:
1: The US doesnt have enough bombs for such an idiotic strategy
2: The nukes required for such a tactic would wipe out your south Korean allies, and hit china, a country upon which your country relies for cheap labour, making such an assualt economically damaging as well as a trigger for a war you cannot win.
3: A chain reaction from NK's nukes could cause a greater damager radius, making the above reasons more urgent
4: I thought you americans were seeking to build an empire, so how will destroying fertile land help you in the long run, at the very least the NK's will give you slave labour after you conquer them.
5: The moment you prove your stupidity, is the moment the world will rise up, all your child labour, you intellcual empire, your anti dirka dirka missions(and the troops Bush is forcing to fight them) will be annihilated by Indias Nukes and other pissed off threats, hell, maybe the Germans will slaughterthe marines stationed on there homeland and pull out of Afganistanso they can join the fun, soon the world's armies will be too close for nuking, then what? dont count on Canada's support, they are usually smart enoght to choose the winners, so we'll be with Germany and the UK, and you will be dead, so dont nuke NK.
