The Carl Vinson is in Manila bay as we speak,so we are either really concerned, or not concerned at all.
Duterte is surely a threat to Philippine's democracy.
But the fact that US intelligence tag him as such is more related to geopolitical concerns than anything else.
Edit: An interesting observation: in western media Duterte is corrupt, cruel and despotic. In Chinese media he is portrayed as a man doing the necessary evil for his country, promoting cooperation and rejecting western imperialism. I wonder how the locals see him.
I'm pretty sure 99% of the politicians in the Phillippines could be classified as a threat to democracy.
It is a ruthless party-boss, runs in the family and any threats are dealt with kind of a place.
Except the real reason he’s being tagged has probably nothing to do with democracy or whatever version of democracy the US envisioned.
Its probably for being too lovey dovey with the Chinese especially on the disputed waters subject.
Democracy huh? America seemed pretty fine with Ferdinand Marcos running the Philippines, who was literally just a dictator period.
