"(i was the original poster of the north korea argument) i feel that north korea would do pretty well because they have a proportionatly huge military, an airtight border, and are pretty isolated geographically as well. i didnt get as mathy with it as you did so these were just my thoughts."
Now, that got me thinking... which country do you think has the best survival ratio? My guess is Switzerland
It's a cold country with many mountains.
It has compulsotory conscription, so every adult has basic military training. Every adult keeps his or her weapon at home. They have huge underground facilities from the cold war and I think it's the Red Cross central, so they must have a good stockpile of medical supplies.
