This is something NATO can't replace.
NATO doesn't have AWACS. For these early warning and control radar aircraft, France has 16, Poland has 2, and Sweden has 6 compared to the US's 87.
Expect the US to turn off GPS next IMO.
NATO had depended on different member countries to specialize in different areas. This was the sector allocated to the US.
The only reason France has nukes/some radar planes/military industrial complex was Degaulle's distrust of the US. Looks like he was right.
This is after both Zelensky and parliament made public concilitory remarks to Trump.
