Last month, in the latest escalation regarding the South China Sea, Philippines President Rodrigo Duterte threatened to give notice to the United States to end the Visiting Forces Agreement (VFA), which allows American forces to train in the country, if the reported cancellation of the visa Senator Ronald dela Rosa, was not reversed within a month. The outspoken leader said in a speech on January 23: “I’m warning you. If you won’t do the correction on this, I will terminate the Visiting Forces Agreement. I’ll end that son of a b***h.”
