This is the literal, specific scenario 2A was intended to counter. We’ll have to see over the next few years if it works as intended.
I’m not sure thats right. I think the 2A was written in order to enable the US to be able to organize militias to defend itself against foreign invasion as, at the time, the idea of the colonies supporting a standing army was impossible.
People invoke 2A usually lie, and the reason to arm themselves is to kill dark skinned people they don’t like.
The US don’t have a few years it will probably not exist at the end of the years if nothing is done
