It's not that simple. Because enemy nation states also have their own satellites. They will just be damaging their own infrastructure, specially Russia with their huge land to cover they need their satellites.
Perhaps one side temporarily blinds a spy satellite with a laser[1], to prevent it from observing something sensitive. Then the other side reacts by blinding another satellite in the same way, but oops, the laser was a bit too powerful and it does permanent damage to the sensors. Then a single satellite is outright destroyed in retaliation. Etcetera.
