Thanks to our “progressive” regulatory system, we did everything but outright ban mining for them (though the “progressive” regulations wound up becoming in fact, a de facto ban).

Not surprising. Do you have a good reference?

Unless you’ve got news to the contrary, we have finished refurbishing our biggest rare earth mine and it’s opening up this Summer (See: Mountain Pass mine). http://www.bit-tech.net/news/hardware/2011/07/04/japan-finds-rare-earth-mineral-deposits/1 also reveals a new rare earth find in Japan that increases world supply 1000 times.
Human beings usually can't see that radiation or feel its effects, but we have a relatively low tolerance for the stuff ~ so all the existing rare earth mines in the US were simply shut down while the ore processing steps were improved to remove dangerous radioactivity first.
China is doing something quite similar. Most of their operators were taking no care to protect people from the radiation danger ~ because, as it turns out, in China they don't particularly care about that one way or the other.
I think some of the big dogs do care because they don't want to eat any of it in their morning ricebowl.
Now the Japanese are different. Most of them are very concerned about radiation ~ at the same time they need rare earths ~ so while they're up to their armpits in alligators up there at the radioactive Tsunami site they'll start mining this stuff anyway.
They will continue to be very concerned.
