I don’t think Trump will make a deal that won’t ultimately end up benefitting us. Besides the national security aspects he’s touting, he’s eyeballing the natural resources that can be exploited which will help pay for whatever it ends up costing. He’s not used to being taken advantage of.
He himself pointed out that the natural resources aren’t that much, buried so deeply under ice—and with “rare earth” being something of a misnomer instead of the more relevant “rare processing” of key minerals.
But yeah, Ron Lauder, the billionaire head of the World Jewish Congress is the one who first brought it up and convinced him that it was needed—and Lauder has business interests there.
