But it is more than simply defending hearth and home.
It is defending the nation, or the populace.
The 2nd Amendment gives us the rights to any military weapons.
Yes, any.
If you can afford a stealth bomber, you gave the right to it.
Tank, nuke, machine guns, missiles.
It’s not about hunting or only protecting an individual domicile.
The whole people were to be the Army; this is true. But the term "well regulated militia" means that this is not an unorganized rabble; it means they get "regular" practice, drill, and preparation. As to what that means in terms of B-1B bombers, I don't know but I suspect the Founders thought that to be an issue for the States to manage.
Interestingly, there was no provision in the Constitution for enforcing States to uphold their responsibilities to provide, train, and supply a fair contribution to the national defense. Moreover, I shudder to think of how 48 competing States might have organized sufficiently to fight WWII, compatible ammo and all. We surely do have a national standing army. So perhaps technical reality might warrant an amendment there.
Or be it a sword, a knife or bow. Arms and the 2nd apply to all weapons.
Actually, it means any weapon that an infantryman might carry; not a weapon of mass destruction.
It’s really about protecting us from a tyrannical government.
Really?
I don’t think that you can “bear” any of those crew served weapons. Neither will the courts.
In “Miller” the USSC ruled that the 2nd protects weapons that have a military use.
