Wait, is this new? I was pretty sure it was known since like the 90s that both Russia and China had anti-satellite satellites, to say nothing of the ground and plane launched missiles. There was a satellite destroyed like a decade ago I think that was strongly suspected of being a test firing of some countries satellite weapon.
The big problem with these things isn’t that they exist, it’s that usage of them leads a very strong chance of triggering a Kessler cascade, and then everyone’s going to have a bad time.
