Yes, correct. The current administration is normalizing military acts of very questionable legality. On any given day it’s tough to tell what the next incremental escalation / edge case will be. SOUTHCOM is currently postured in a way that only makes sense if, most charitably, the U.S. wishes to appear prepared to imminently launch a war of aggression on someone in or bordering the Caribbean.
It is never, ever wrong for civil authorities - executive or legislative - to remind a professional military to be mindful of the law and what it says about how they act. It’s regrettable that it’s increasingly necessary to.
