It's true. I wonder how many ancient Babylonians, Greeks, Chinese, Egyptians, Persians, Romans thought:

Especially in modern times it's insanely difficult to imagine the geopolitics shifting drastically, but it's happened before, it's happening now. The difference being that the rest of the globe is now much more invested in your shenanigans with your neighbors, but it's still happening.

I'm glad I've never had to seriously consider it until now. ...but it unnerves me that I probably need to start.
I would agree, although a human with an AK is still a human with an AK. Even unskilled, undertrained, under supplied infantry should be taken seriously because they're still a large number of bodies that can pull triggers.
