They definitely are interesting. A little terrifying but definitely interesting. What happens when the world you live in isn’t big enough for the weapons you have? :-)
We are not there yet but at some point SOME of the weapons created will be of more use for battles between planets than countries
Or the moon once colonized. That is why I agree with Pres. Trump creating the new military branch, SPACE FORCE. We are already competing with various countries regarding satellite destruction. The US needs to take dominance of close/outer orbits and beyond. Space is truly the final frontier, and will eventually be where wars are won or lost.
There was a movie where a bunch of old-time astronauts were sent up to stop the decaying orbit of a Soviet era comms satellite. Turns out is was nuclear missile platform. I suspect such platforms are being designed if not already in production.
