Regarding USAID: That is under Rubio now, who was confirmed unanimously. So I suspect it will be resurrected in some form and continue at least regime change operations.
MAGA outlet Tucker Carlson had Mike Benz on this week. Mike Benz had been vocally opposed to all CIA or foreign interference programs during the election campaigns. This week he recanted, talked without his usual eloquence and said that USAID is not all that bad! So MAGA is being reprogrammed.
If nothing really changes, the Democrats (who were avid neocons in the past four years) won't mind. Which could explain the meek protests of Schumer etc.
The treasury story is way more difficult, we have to wait for more information.
