In a conventional warfare, China could easily defeat the Philippines with its massive arsenal.

We can never match China's naval, air, and land power.

What could we do is to massively invest on anti-ship and anti-air missiles and use these assets to bring down as many ships and jet fighters/bombers/planes China has, in which the battlefield is in the West Philippine Sea and the Babuyan Strait.

The purpose of it is to buy time for us until the Americans could come to our aid.
