alt Hacker NewsWell. I can't talk for the current government of Sweden, but if I was the supreme leader of a Swedish Dictatorship, I am pretty confident that I could accomplish that by sending some very persuasive soldiers along with a government officer with some papers ordering those private companies to do whatever the fuck I wanted unless their executives wanted to experience some extra holes in their bodies.
Luckily Sweden is not a dictatorship and doesn't have a supreme leder. Our government can't just hand-wave things. There's the legislative branch which must've had the foresight to make laws that allows the executive branch to order operators to comply.
The parent asked "Which technologically advanced democratic countries DON'T have this capability already developed and deployed?" and there are many, every country on earth isn't run by warmongering corrupt idiots.
