ICE is no longer an immigration agency. It is a paramilitary force, backed by a parallel prison system, answerable to the president alone. Whatโs happening in the U.S. isnโt a deviationโitโs an infrastructure. And it wonโt end with Trump.

If accurate, this raises the question "who is governing Venezuela right now, and tomorrow?" (The answer isn't "Delta Force" or "SEAL Team 6," that's not what they do.) While nearly every state has a presidential line of succession, that may not indicate where power actually lies in coming days.
