I think its for the best to find new rare earth sources outside of China now anyway, before any great power struggles.

There are lots of sources; it's just very environmentally damaging and/or expensive to extract them. And so far China could, for various reasons, do it way more cheaply than most others. Seems this is going to change...

Or the battery minerals/components rules for EV tax credits

This is really the best they could come up with?
