The pentagon has plans to fight/battle/war with EVERY country. North Korea, and Iran are obvious even if we aren’t fighting now. For some reason people were surprised a few years ago when it came out that we have plans in case Canada attacks. Even if unlikely we need a plan to start with rather than starting from scratch if it looks necessary.
It shouldn’t shock anyone that they have plans to battle US citizens if/when needed. And limiting the arms citizens have access to is certainly part of that plan and they can start working on today. I’d bet US citizens are in the top 5 on the list of concerns the pentagon has on for attacks on the mainland in the foreseeable future (and Canada isn’t top 5 and they have a plan) .

Contingency planning is there for “all” threats foreign and domestic. With so many plans made, they ran out of colors.
