President Rodrigo Duterte threatened Saturday to terminate a pact that allows U.S. troops to visit the Philippines, saying “bye-bye America” as he reacted with rage to what he thought was a U.S. decision to scrap a major aid package over human rights concerns. A U.S. government aid agency, the Millennium Challenge Corporation, said earlier in the week that its board deferred a vote on a renewal of the development assistance package for the Philippines “subject to a further review of concerns around rule of law and civil liberties.”
