I'd say intentionally destroying space assets etc should be considered an act of war (compare attacking another nation's ship in international waters), NK wouldn't have a chance and they could be put into space lockdown where any launches are intercepted.

Good luck dragging people into war over space trash that doesn't even benefit most peoples' lives in any material sense.

Are you sure that you have never looked at a weather forecast (or received a severe weather warning), crossed an ocean in an airplane, used GPS (or another satellite-based navigation system, or eaten food farmed using precision automated equipment that does), which are just the first things coming to mind that would be much harder without satellites?

Do you really think people will want to go to war to protect America's hegemony of gps?

I believe the US would almost certainly go to war if there were an intentional attack on GPS.

The us goes to war if someone sneezes.

It is even worse than the analogy, because every bit of mass from that sunken ship becomes drifting naval mines.
