I was just curious about locations to take shelter/reside during a possible nuclear holocaust. I've heard and read many times that the Cheyenne Mountain Operations Center (or Cheyenne Mountain Directorate as it's known now) is the safest place to be in the United States during the third world war. The argument used most to support this theory was that in case of a nuclear exchange the president, vice-president, other government officials, ''important'' civilians and their families take shelter there and were able to stay there for years to come (thanks to water/air purification, durable electricity and a vast supply of food). Now I was wondering what the safest place was in other countries (like Russia, Great Britain, Germany, Japan, and others). Does anyone know this?
