Space is more like international waters legally. The outer space treaty is rooted in maritime law principles. The Chinese and Russians are in no mood to slow down relative to the US. There will likely be some escalation in debris and damage resulting from that might eventually result in some kind of action. But most of the damage here would be economical and sending more stuff up is now very cheap. Manned flight is relatively infrequent and aside from the space station and very short lived space tourism, most activity in space is unmanned.

So, if a lot of satellites get taken out that's a problem but if a few get lost, nobody will care. The space station and other important stuff can be in relatively safe orbits. There's also the notion that a lot of the debris in low earth object comes down pretty quickly. Lots of unstable orbits. LEO is where most of the activity is for things like starlink and competing constellations. Which moderates the risk a bit.

SpaceX satellites are doing about 1000 collision avoidance maneuvers every single day. The addition of new networks is going to congest things even more and the risk of unavoidable cascading failure keeps increasing at a massive rate.
