Aliens? nuclear war? tidal wave? global warming? zombies? civil war? global pandemic? terminators? what do you think the apocalypse will be? i can see two of the above happening: terminators and civil war. It's only a matter of time before some scientist develops a self-thinking robot that goes nuts, or a killing machine that some psychopath successfully programs to kil people. also, if the stupid people of this country continue to blindly follow a political party were likely headed to civil war sooner rather than later.
