This guy is an exhibitionist. When the Philippines wants something from the US this is what it does. Duterte will wash away like soap. Ten million Filipinos live in the US are a permanent, Duterte is a 5 year one trick pony.
He's popular domestically because he's gone for the popular visible social evil. Aquino went after the unseen root cause of economic malaise.
One president will be remembered and one forgotten.
