But that's a relatively recent phenomenon, though. The US has had a strong military history, but the 'citizens need guns to fend off our government' thing has only been frothy for the past little while.

It's not going to go away either, until the US kicks the societal idea that problems are best solved by men with guns. It's going to take a long time for that to ebb away, even if public opinion were going in that direction.

Gun control laws won't work even if they're brought in, because handguns will never be a part of them, and it's handguns that do three-quarters of the firearm murders in the US. So there'll be some pissweak restrictions eventually brought in about really fringe longarms, and they'll do nothing to solve the problem.
