Having insulted United States(US) President Barack Obama and all of the American people, Rodrigo Duterte and the Filipino people who continue to support him, should be abandoned to the current of the South China Sea.[Duterte's insult will not be repeated on this Blog.]
The US has never needed the Philippines. The Philippines needs the US. Thus given the derogatory comments the Philippines president has claimed against the mother of US President Barack Obama, maybe the US should determine that a better ally on the East China Sea is more civil and kinder than a brute on the South China Sea who will always have natural and non-natural disasters to navigate and to survive.
Filipinos could save themselves from the damnation Duterte is bringing by rebuking and rescinding his rule.
