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.

The 2nd amendment made sense when the enemy was a group of people across the ocean (the British), and other groups of people from across the ocean that they hired as mercenaries (the Hessians). Keeping the common people armed to be used as foot-soldiers in case of foreign invasion is not a bad idea if invasion is a serious concern; Switzerland still does this to this day.

For protecting against your own government, it really doesn't make that much sense. Your own government has to have support of your own military, which gets its members from the population: the military is made of your own neighbors. If your military is committed to the government and doesn't mind shooting their own family and neighbors, then you have a problem that arming people with small arms isn't going to solve: the rebels just aren't going to be that numerous. More likely, the military isn't going to support this action at all, and will mutiny and either implode as different factions within the military fight each other, or the military will stage a coup and take over the government (this has happened before many times, in other nations). In short, if the military supports the dictator, the armed opposition really has no chance of winning. If the opposition has a chance of winning, they don't need weapons because the military isn't going to support the dictator.
