But as an aside, I can understand the mentality of resistance against tyranny with the purpose of retaking the country. And I don't think it's outside the realm of possibility.
Couple of things here.
First, we gotta differentiate between military occupation by a foreign force and brutal dictatorship. I was talking about the second one. It's one thing for a guerrilla to exhaust the will of a foreign country to occupy your country and quite another to overthrow a tyrant who can't just "go home" and forget about it. These are two very different situations. Tyrants generally don't go easily, and that difficulty seems to increase the longer they've been in power and the more people they've killed or imprisoned.
Second, modern tyrants not only tend to command the loyalty of the security apparatus, but generally have also gotten the power through that loyalty. Just about any coup you can think of in the past 30-40 years has been accomplished either by the army, or by someone who had strong support of the army. Likewise, situations where tyrants have been brought down generally divide into two categories. Most common one is that they lose the loyalty of the security apparatus who then brings them down and sometimes actually turns the country over to a democratically elected civilians. The other one, which seems to happen more in places like Eastern Europe, is that mass protests lead to undemocratic governments falling.
What does
not happen is armed private citizens banding together and then using their handguns to somehow defeat the security apparatus and restore/introduce democracy. That's actually ludicrous to even consider. Look around the world. Assad has an army. It may not be much of an army, but they have tanks, they have officers, they have weapons that in no country in the world are available to private citizens. The only reason the opposition has been able to do as much as they have(though they're still going to get crushed and lose and all of this will have been in vain) is because they've gotten weapons from the outside and because they have managed to seize some of Assad's arsenal through defections of the Sunni Arab part of the security apparatus. You can't take cities with handguns and hunting rifles and you certainly can't defend them with handguns and hunting rifles.
Personal arms will not help you if you can't either get a foreign country involved or the army and the police to come to your side. And they can't help you make those two happen, either. It's just a red herring, really, the whole argument that you having a gun is some kind of a bulwark against tyranny. It ignores the cold, hard reality of the modern world.
