Switzerland is also the only country in the West which is fully prepared to shelter and preserve its entire population in underground shelters for several weeks, in the event of an all-out nuclear exchange.
They long ago built and stocked entire underground cities, complete with plumbing, electricity, stored weapons, bicycles, etc... cut deep into the mountains, and they keep them maintenanced and up to date.
The Soviets once did the same, but only to preserve their Kremlin leadership.
Just recently, the U.S.A. has copied the Soviets...made sure that every piece of drek in Washington can live in an underground city, but they haven't so much as spent a penny on civilian defense.
America's leadership is so stupid, that right after 9/11 the IRS sent instructions to all of its field agents entitled "How to continue collecting Federal Income Taxes after a nuclear war".
I am not making this up.
