This whole video is like one big joke to me. What, she's sitting on a chair with black wings as a back? Dramatically! She's talking shit about Iraq (she doesn't know when Desert Shield and Desert Storm ended). And all these suggested conspiracies.. right: paranoia. Isn't that something we know from America? Paranoia here, paranoia there. Safety here, safety there! We have America on the one side, and Russia on the other side. America tries to be prepared for any kind of military strike. Be it nuclear or biological warfare, America must be prepared. I am no American myself, I am German, but I can tell from just watching this video twice that it's just bullshit. The FEMA coordinates everything directly or indirectly related to environmental disasters, and if America was to be attacked with biological weapons, vast amounts of civil deaths are estimated. That is why you need cheep coffins with lids and everything, and completly unused graveyards which can only be accessed by train. The trucks are transporters which have strong armor and can be used as panzers, so they are a good choice in case of a civil war or in case civilians need to be saved.
Long story short: Don't trust anyone who doesn't even know historical facts about his mother country. There is no need for paranoia if the government does this already for you.
