On Kotke.org Switzerland's elaborate Cold War defenses. The Swiss do love to dig a hole. I recall a mate arguing with a Swiss reservist about this. The guy explained the plan for the Russian invasion was basically for the all the men to get their assault rifles and go to the impregnable mountain bunkers. My mate pointed out that the Russians will just start shooting your women and kids until you come out. The Swiss was outraged and pointed out that was really not allowed.
