Well I fully agree with Duterte. Obama is the son of a whore.
The guy ( Duterte) has been under a lot of stress lately. He is battling on two fronts --- Drugs, which are being distributed among the populace at the highest levels of government and of course, a Southern terrorist insurgency named Abu Sayef ( allied with ISIS ) that recently exploded an IED in the middle of a popular night market in the city he used to govern ( killing 12 people ).
I am no Obama fan, but for the sake of the alliance between the two countries I certainly hope they iron things out.
