remember WWll? the japanese bombed us because they thaught that with all the different kinds of cultures our country has that we wouldnt be able to do shit. If something really goes down im sure we will have alot of people volunteering. Also, I am not worried of a land war in the USA. Sherm is right. Other countries know we are armed to the teeth and will fight with every last bit of breath in our bodies if someone came here starting shit. Not to mention terrain advantage.
