In 1989 or 1990 during the operation to oust Panamanian dictator Manuel Noriega, a US infantry unit in Panama City broke ino the Nicaraguan Embassy, believing there were Sandanistan weapons in there. There was hell raised and Ortega declared a bunch of US diplomats, some friends of mine, personae non grata and expelled them in retaliation. It’s a serious infraction of international law.
International law? That’s a joke. Just another means of shielding dictators and tyrants.
