Occam's Razor: offshore wind requires a lot of rare earths for their magnets and whatnot. US military-industrial complex needs the little remaining global supply not under China's export controls.
compared to the general motor market in the USA? I think thats out by a few orders of magnitude.
Radar shadow is vaguely plausible, if your radar is shit and needs replacing.
it also requires your hydrophone network to not be working that well either.
So any source of electricity that may replace these wind turbines (other than solar) will require about the same amount of rare-earths. And lets face it, Trump is doing his best to hamstring solar as well. He has cancelled all solar subsidies and has hit solar with major tariffs.
I think Occams Razor would lead to a very different conclusion.
AFAIK, not all kinds of rotating generators require rare earths; IIRC, induction motors don't need any permanent magnets.
