When needed.
Which is technically what 2A is all about. The rest of it is just things we do to keep skills up to par.
I’m not fully defending the post, but it is a consideration is some ways. I do not hope for a war of any kind on our own soil, but I also know that there is always the possibility of that occurring some day. I think the anti’s have it their heads that the world is too civilized for that to ever occur. Even with signs of it all over the globe they feel if they just don’t believe in it, it can’t happen. Nobody would ever attack us and a civil war is impossible. The rest of us or most of us hopefully, know anything is possible. We do not hope or wish for it, but we should be prepared for it.
Some just say it a different way I guess.
