The asymmetric vulnerabilities are simply because USA has so much more satellites compared to everyone else that give it various economic and military advantages. This means that an escalation that wipes out all space resources for everyone is effectively a major loss for USA, as they lose a lot of capabilities, investment and comparative advantage, while those who had less resources up there did not suffer much because they had much less to lose; If anyone would be starting a major land/sea/air conflict with USA, then taking all space stuff out of the picture would be very useful for them.
