#2"rare earth metals" aren't "rare" to the USA
They are "rare" per ton of earth in general
So it's just that mining them is so labor intensive and so toxic (uranium and other radioactivity) that it is expensive outside of places like China.
Automate that with bots or whatnot and maybe we don't have to invade Canada and Greenland and start WW3

#3It is an attractive industry, but sometimes can be repulsive.

I think we could just regulate the industry properly and then find out what the actual cost is. It may have to be subsidized. With that said, I wouldn't want any new mining operations started in my state.

I know you're being facetious but it's also worth spelling out somewhat explicitly as well: the US has never had a supply problem like that because through effective diplomacy and alliances it has commanded an excellent position to negotiate as a preferred trade partner through its world leading expertise in many areas and the export of its military spending as a security partner which up till very recently ensured alliances like NATO would prioritise these sorts of issues in its favour.
The very recent turn of "we must literally own this territory" has been the surest possible way to create a crisis where none existed.

#7It seems amazing it has taken this long. Electric motors are so critical to national security, as well as the US economy.
I keep wondering if these folks have a realistic alternative: https://www.nironmagnetics.com/ (They claim high performance rare earth free magnets.)

#9More interesting to me is Niron Magnetics, mentioned in the article, which is commercializing magnets based on a particular phase of iron nitride.

#10Any motor experts here? Why are they chasing rare earth metals in the first place? In the end, the mines are going to be in China anyway, right? Why don't we design around rare earth magnets in the first place?
Synchronous reluctance motors where torque density isn't a strict requirement, and brushless separately excited synchronous motors (synchro motor with electromagnets on the rotor) for high torque/energy density applications?
