Since (similar in some respects to Switzerland) virtually everybody who moves to Israel or is born there is a reservist, it isn’t as onerous as one might think. The place bristles with weapons in more-or-less honest hands. My own father, when he visited Israel, said he had never seen such a safe place — nobody would dare rampage with a gun.
In the US, military participation today is quite voluntary. The US Constitutional authors had a good answer for this, which was to deem all able bodied males the militia, which must not be deprived of their weapons. (In principle. The practice has deviated grievously.)
True enough.
Even here in the Czech Republic, the notion of going on a gun rampage is not a good idea. Lots of folks have a concealed carry permit. Getting one isn’t easy to be sure, and there is no “shall-issue” provisions in Czech law. If you want one, expect the Federal police to talk to your neighbors, your spouse/partner, your co-workers, and you can expect to have a little chat with a Federal police shrink.
And you must also demonstrate the ability to field-strip and reassemble your firearm to a Federal police firearms instructor, and of course proficiency and safe-handling.
Here you’re not limited as to the amount of ammo you can have at home, unlike Switzerland and Israel, so in that sense, it’s a bit more relaxed here. Of course registration and licensing is mandatory.
It’s still the law. Google USC unorganized militia.
