Even if that minerals deal with the US secured Ukraine all of their lost territory and a return of their abducted citizens (including children), I would say it's immoral. The US has basically announced they never cared about peace or anyone's sovereignty - it's only ever been money. Vile.
But to be all about "compelling commercial opportunities"... with one of the most corrupt nations on earth run by one of the most brutal authoritarian regimes on earth, the guys who started the war... it's just unbelievable. A whole new layer of unbelievably disgusting crap coming from Washington.
