Trump being so open about imperialism will make it easier to convince people that the US war machine is about profits, but it also makes it easier to convince them that imperialism is necessary to maintain their economic privilege.

I don't think those minerals will benefit anyone but the ruling class, but your average American could be easily convinced they will.
