It didn't have a fallout shelter. It had a blast shelter capable of surviving a Hiroshima-sized blast 300m away.
The Switz have a “honeycomb” defense. Every man of military is a member of the militia. There are uniformed men with their FNs or some other fine individual weapon always going about. Every home has these weapons and their ammunition. There is nobody with the authority to surrender. You’d have to defeat every valley of Switzerland. Neat and orderly. Electric fences are placed on yards so one or two sheep can graze for a day, or a cow. On a rail excursion - just gorgeous - I only saw one wall with graffiti. I was embarrassed as, I thought, that could have been done by an American. Something like this militia approach is being adopted by Poland and other front line countries based on the success of the Territorial Defense Force in Ukraine. Let us, the people, take ownership and responsibility for our country.
