Check out the policy of mandatory service, and in fact the overall military philosophy, of Switzerland. A fascinating approach to civic responsibility, and the overwhelming majority of Swiss are on board with it.
As an aside, Switzerland is probably the scariest place for an army to try to invade, with the possible exception of the US.
Would that have anything to do with the (excellent) fully-automatic assault rifle hung over every boy and girl's fireplace, and the 600-round can of ammo in the closet?
Once saw a National Geographic article on Switzerland from the 1940's or 1950's. One interior photo of a Swiss home showed three generations of military rifles, from an elderly Schmidt-Rubin to the latest model, hanging over the mantle. Each one belonged to a certain family member of a different generation.
Of course, Charlie Schumer and his playmates from the Violence Policy Center would have a cow over the numbers of guns in Switzerland and the utterly irresponsible way in which they were kept right out in the open, in the living room no less!
