1) Nukes, big bombs, tanks, and rocket launchers do not operate themselves, and the humans operating them are vulnerable to small arms, so they carry their own small arms 2) Nukes, big bombs, tanks, and rocket launchers are crew-served and nearly always collateral damage-causing weapons, which means they are not covered by the 2A for individual keep and bear. However, when the government takes the cold civil war hot, the 2A will no longer matter as a legal defense against categorical infringements against the right to self-defense. People will either use whatever weapon they have or can loot to defend innocent lives (regardless of whether it is crew-served or not), or evil will win.
Please please tell me that's a joke and that you really do understand the blaring fallacy with that argument.
Oh, you're right, nukes, big bombs, tanks, and rocket launchers are all fucking controlled by Skynet, not humans. Nevermind! /ignore
You are not shooting down an ICBM with small arms. You are not shooting down a cruise missile with small arms. You cannot destroy an M1 Abrams with small arms. In fact, good luck destroying an Abrams with anything but another Abrams. And yes, you could kill the operators... If they open up the door and let you in. Otherwise they'll just laugh at your second amendment and tear you apart.
The only heavy weapon you could take would be a rocket launcher. But that's useless against any of the other things listed.
Many seem to be implying all military and government and private contractors are traitors who will commit genocide without question, and that you can't get inside things from the outside.
Wrong, and wrong.
When did I imply that there would be a genocide? If there was a revolution, of course the government is going to fight back... It wouldn't be genocide, but they aren't going to send the rebels flowers and cookies.
And I assume that by the "inside things from the outside" you're talking about buying from contractors? Because contractors don't have access to the plans of the weapons they build most of the time. Instead each section of the factory has access to a small piece, and together they build the weapons or vehicles without knowing the entire blueprint.
