>You can bet they would retaliate, simply because the game theory aspect of all this implies there needs to be a severe cost associated with damaging US infrastructure.
It doesn't necessarily imply that that IFF Starlink is providing military assistance to Ukraine, and in response, Russia targets Starlink satellites, that the US will necessarily escalate further. And there is precedence for this. For example, after US assassinated Soleimani, and Iran retaliated against an American base in Iraq (leading to ~100 casualties - though no deaths, and extensive damage to the base itself), America did not further escalate.
