Yeah let's see how that works out for you.
It won’t, Maybe Uncle Donald will fix it...(?)
Here's the problem: Obama has made the US so unreliable and unpredictable that the Phillipine government has no idea (or faith) that he will support them in anything. And there they sit with "disputes" with giant China. China will gobble them up if they want to and the USA will probably (under Obama) do nothing but give some speech about how mean they are and how a sternly written letter is on the way to the UN right now.
They decided to align with China now when they had some ability to negotiate the terms rather than wait for the inevitable.
Bottom line: Trump is right when he says nobody respects (or trusts) Obama / Clinton.
The Philippines is a rather strange case. The country has sent out professionals all over because there are no jobs at home. There is great education but it is wasted in country.
The other nations have emerged and gone forward while stagnation reigns in the Philippines. There is class separation of rigid proportions. That results in political corruption of the highest order.
There is also a large Chinese population. I would suspect that this population having strong commercial connections has decided to throw off the traditional rigid classification and firm up relations with the mainland.
None of that means the PhilChi’s are communist. Just the reverse. They are working with the Chicaps that are emerging as the real power.
China will have Duterte Two Joys for lunch.
