As I've said before, my working assumption is that the goal is the North American Empire under Donald the First. If you're on the Donald's side, it doesn't matter how you justify the walls at this point, so long as the walls go up.

Isn't this the case where the DOJ's argument is "Neither we nor the Salvadorans can find him"? With a sort of implicit "No one's actually keeping any records"?

One China in theory, two in practice. For example, Taiwan has long had permission to buy almost leading edge US weapons systems that China would never get. Taiwan has purchased both Patriot and HIMARS missile systems. There is active discussion to let them buy Excalibur artillery rounds. Remember when F-35 deliveries were curtailed after it was discovered that some parts supplier had included Chinese magnets? The F-35 incorporates integrated circuits fabbed in Taiwan without any complaints.
