Considering during the y2k scare, people were building bunkers and stashing weapons,
all for a clock malfunction.. then yeah, I'm thinking between mankind's lost marbles and scruples.. a war isn't discountable.
Trouble is, the weapons are far nastier now, than during WWII.
Wouldn't surprise me if it went nuclear or biological, despite the "rules" of war (laughable) barring them. Rules only work when everyone
plays by them.
All I know is.. if it happens, I'm buying a German shepherd and naming him "Dogmeat"
