Ars Technica: Why a strike on Starlink would boomerang onto China and Russia's own satellites

The boomerang physics of low-Earth orbit as a shared commons makes a serious counter-satellite campaign against Starlink self-punishing for the attacker, according to expert analysis reviewed by Ars Technica. Starlink's value to the US military (navigation, communications, missile warning, tactical targeting) is what makes it a tempting target. The mechanism experts describe unfolds in layers: a debris field from kinetic strikes would threaten every operator's assets in similar orbits, including China's and Russia's own LEO networks; electromagnetic jamming that disrupts Starlink can also disrupt the attacker's reconnaissance and commercial-bandwidth dependencies; and kinetic action would hand Washington a clear casus belli for retaliation.

Ars Technica's analysis (built on a joint investigation by The Insider, Der Spiegel, and Le Monde) calls this a boomerang. A slideshow from a 2023 China-Russia Military-Technical Cooperation Forum, described in the joint investigation, presented coordinated planning against Starlink. Read in the language of power, it looks like aggression. Read in the language of physics, the expert analysis suggests it is a hostage note the attackers have written to their own future in orbit.

The pattern is older than Starlink. When critical infrastructure sits in a shared commons (sea lanes, undersea cables, orbital shells) the threat to attack it is itself a deterrent, because the attacker's own interests run through the same pipes. The next decade of space-war headlines will keep announcing counter-satellite breakthroughs. The reader who knows the mechanism does not need to wait for the demonstration.
