When Mike Griffin started the Space Development Agency under Trump in 2019, he said we need LEO constellations to track hypersonic missiles and be proliferated to be robust against anti-satellite tech.
However, existing MEO satellites have proven capable of tracking hypersonics just fine. Meanwhile LEO satellites are way more vulnerable to ASAT, they can be directly hit. No... LEO only makes sense when you look at Mike Griffin's history working on the Strategic Defense Initiative. He sees LEO constellations of sensors as the first step to including space-based kinetic interceptors (hypersonic reentry vehicles, aka space weapons) which need to be close to Earth in LEO to work. He is part of the hawks in Washington trying to build a space-based power projection system for boost-phase interception and prompt global strike.
The whole thing seems built on deceit.
