What happens if someone decides to flex their ASW in a demonstration of capability, and accidentally triggers a Kessler syndrome situation?
Additionally the US and NATO would see an act like that as barely one step below declaring nuclear war.
If anyone in NATO considers blowing up satellites to be one step below killing hundreds of millions of people, I want that person fired. Because they have completely lost touch with reality, and should not be allowed anywhere near a weapon, or a job where they manage people with weapons.
The reason taking out spy satellites is taken so seriously is it is considered a likely prelude to an attack.
I'm sure people are wargaming this.
