Grift Or No Grift?

From Friday there was this...

In a retaliatory move, president Trump threatens 100% tariffs on Chinese goods.  The president made the threat after Beijing imposed new global restrictions on the use of rare earth minerals, which are vital supplies for U.S. makers of chips and batteries.

Just curious how many Trump family members and cronies shorted the market before his tantrum?

On a serious note, restrictions of rare earth minerals is a big deal with all sorts of implications.  Canada holds some of the world's largest known reserves of rare earth elements (REEs), with an estimated 15.2 million tons of rare earth oxide in 2023. Unfortunately, very little of this is being developed.  Rather than working co-cooperatively with our friendly neighbors to the north our president has adopted an adversarial and belittling attitude towards Canada; creating unprecedented resentment toward his administration by Canadians.  Naturally, what do I know?

This is revealing of the administration's lack of coherence on this subject.  And the only response is a Trumpian fit of pique and threatened tariffs?

Is it just a big grift?  Or sloppy deal-making?

Monday will reveal more..... 

EDIT TO ADD:
