They have to be invited. FEMA is weird as heck. I did some fema disaster preparedness certifications for a scholarship program I was in. They had FEMA courses on weird stuff. Like establishing a government after a nuclear holocaust was one I did.
They had a tongue and cheek one about a zombie outbreak everyone always talks about, but the ones about nuclear war, total government collapse were the real conspiracy weirdness.
Alex Jones ranting about fema camps has some truth to it they’ve had a lotta weird creepy plans.
We had something from that area of knowledge in Soviet school, but it was combined military/survival preparedness lessons where we was teached everything from how to disassemble/assemble AK47 and use it to PPE stuff and how to get clean water in case of disaster using things laying around. It named "Basics of Military Training", and was mandatory for both boys and girls. Nothing weird, really. Of course with grain of some politics and learning ceremonial steps, but overall now I still think it was useful and sometimes fun. Still could disassemble/assemble AK in less than a minute. :) And most of girls from my class still could too. :)
