It's the standard approach of this regime: at some point or another, claim EVERY possible reason for taking an action. Then, when one of those comes true, claim that you were right. It's like picking both the Eagles and the Chiefs to win the Super Bowl....hell, picking them both to win in the same sentence, even. Then, when the Eagles win...you were right! See, he's a genius, he was right! Or, if the Chiefs had won.....see, he's a genius, he was right!
There is no reason here. Just a use of another arm of policy as a blunt instrument, treating 1) every other person and nation in the world as an enemy/adversary, and 2) every transaction as a zero-sum game, which you can only win if the other party loses. There need be no positive outcome for the regime to claim victory: negative outcomes/suffering by other people and countries will be enough to claim the W, no matter how much attendant economic loss and suffering happens here at home.
