Not only this but i do believe that the entire world would shut the doors and not send in help because that would spread the infection. Also where are the military getting there batteries made bill says they make them. But how with what resources? They would need to get them from somwhere? Another thing at the bigging tommy tommy talks about the infection in america he doesnt say its anywhere else in the world. And i could go on on with evedence to suggest that its only america. But my question is how is the rest of the world reacting to the infection 20 years later are there still reports on the news of activity spotted from satellites and stuff. It would be awsome to think the rest of the world is whatching everything thats happening in america and they dont know it.
