I think this will be a drone conflict. Millions of them, small, cheap, armed with small explosives and designed to seek and take out one person. Made in China where we cannot get at the factories. That is just one scenario. There are a lot of ways drones can be used to disrupt an insurgency. I have to say, I am not having a good feeling about our chances.
We hear about earthquakes and indications of low level nuclear tests in China. Such tests I suspect are perfecting a EMP weapon using a low yield nuclear device. Such can be easily delivered into orbit with smaller rockets. Physicists have testified at United States Congressional hearings that weapons with yields of 10 kilotons or less can produce a large EMP electronics killer. With numerous EMP weapons in space, the world is vulnerable with the click of a mouse.
Imagine the entire Midwest with freeways littered with cars that won’t start and clog the distribution of our vital supplies, like food.
