Protester shot in chest by live police round during Hong Kong protests

> Imagine if the US suddenly had a dictator

This is why we have the second amendment. And the constitution as the thing to which office-holders swear allegiance to rather than to "the party" or "the president".

I always find this sentiment a little silly - if the US President went in to full dictator mode and had the support of the military, do you really think a militia of armed citizens would be anything but gnats against the windshield of the United States Armed Forces? And if s/he did not have the support of the Armed Forces, it would not be a very effective dictatorship and you would not even need guns for a rebellion. I truly do not get it.

The US (with its support of the military) has been at war in the Middle East for nearly 2 decades now with insurgents.

The argument is not that a rebellious citizenry will necessarily win a war, it's that it will draw out a bloody civil war so long and so expensive as to be a form of mutually assured destruction, the risk of which acts as a check in and of itself.

The fact is that the dictator would still win. The rebellious citizenry would live a life of absolute misery, just as those in the middle east do.

The 2nd amendment made a lot of sense when weaponry consisted of horses and rifles, not computer-guided missiles. If there was ever a true US dictator, the 2nd amendment would mostly be used by the oppressed to rob, attack, and oppress one another.

Every war goes to the streets in the end. No amount of tanks or missiles stops this eventuality. At some point you are going door to door with guns. You can't just bomb people from far away with a few missiles and wipe your hands clean of it and call it a day.

The only effective bombing campaign that subdued a citizenry outright in military history were nukes, and if we ever crossed that line as a nation where the government nuked it's own citizens to quell rebellion, we are never coming back from that as a nation. It would leave a scar on humanity. Whatever would be left of the United States after that event would curse the people that did it.

So to your point, the 2A is not antiquated, if the US government had any interest in having an intact territory, at some point it would need to get face to face with the people, and the presence of firearms in the citizenry acts as a check against this possibility, and an escape option for the citizens of it ever got there.
