There is no arms race in the Lagrange Points of the Earth-moon system. I think this is a fantasy made up by bored academics and think-tank people, inventing nonexistent crises because they don't have enough real ones in their fields.
There's no military value to those orbits (or please think up one and defend it!) These are much farther away than orbits people are actually using, and far worse (by inverse-square laws) for any purpose involving things on Earth—communications, or observation. And it's outright risible to suggest the *United States* would want national security-critical communications relays in that sad orbit, when we just obtained a constellation of literally tens of thousands in LEO. Starlink is infinitely more capable than anything you could imagine placing in a Lagrange point.
I suspect the real arms race is between anti-satellite weapons and giant, survivable constellations of cheap unit costs, like Starlink. US has a massive head start. Putting expensive single points of failure in an orbit like L2 is a bad doctrine: that's a sitting duck at the outbreak of a potential war. China quite possibly has already deployed missiles intended to defeat this: they tested what the US thinks were anti-geosynchronous satellite weapons, more than a decade ago [0]. L2 orbits are only trivial amounts of energy more than geosynchronous (cost to intercept–not orbit-match).

- SiempreViernes 2y agoNo, sadly this is a fantasy also made up by the employees of the Space Force, see for example the introduction to the Space Force "A primer on cislunar space" > Until now, the limits of that mission have been in near Earth, out to approximately geostationary range. [But now] the reach of USSF's sphere of interest will extend to 272,000 miles and beyond - more than a tenfold increase in range and 1,000-fold expansion in service volume. [...] USSF organizes, trains, and equips to provide the resources necessary to protect and defend vital U.S. interests in and beyond Earth-orbit [emphasis mine] https://www.afrl.af.mil/Portals/90/Documents/RV/A%20Primer%20on%20Cislunar%20Space_Dist%20A_PA2021-1271.pdf https://www.afrl.af.mil/Portals/90/Documents/RV/A%20Primer%2...
