Since the 4th edition added 2017 EM9 asteroid to the doomsday mix and made it known that it would hit the planet a little over a year's advanced notice the bigger national governments are all going to protect their most important people. They will try to set up special survival arks like in the movie Deep Impact to save their culture, heritage, and way of life regardless of what the odds of survival are. The very best minds, art, etc. will be saved for future generations. Before, in 3rd edition, TEOTWAWKI was a suprise to everybody. TMP was preparing for it and the national governments in the US and Canada put some Special Forces in freeze tubes to maintain the democratic way of life just in case the fools were right. Otherwise, people lived their lives out as normal and the government continued to function cutting taxes, trickle down economics, etc. In 4th edition the asteroid changes all of that. There is foreknowledge of the disaster and people and governments will react differently. (Borrowing from the movie Deep Impact, the survivors in the ark in the limestone caverns in Missouri could morph over 150 years of time into the "Frozen Chosen". Another ark in the Rockies could have been the start of the "Breeders".)
