surely you can show me a shittone of examples of such a massive campaign of kidnappings happening to people forbidden from leaving the country [...] that happened in [...]let's say last two centuries?

I'll just give you a partial list of European countries that 1) had wartime conscription, and 2) executed deserters, in WW1 or 2, which would indicate an equally/more drastic "kill or be killed" choice, and is way easier to find. Or do you know better how conscription worked in the WWs off the top of your head?

• Britain and the Commonwealth
• France
• Germany
• Italy
• Soviet Union (estimated around 150 000 executed in WW2, including returned POWs executed for "desertion")
