The book of art of war duterte knows it that is why he play in international arena in the whole world. To get what he wants for the better future of the Philippines. Unlike before Philippines will be soon rise in the sky. I hope people in the Philippines listen to this leader. I hope they will not corrupt in their respective agency.
Yes I beleive in Duterte's tactics especially on scarborough shoal. If he pursue the decision about island dispute I think Philippines will be a land of war between US and CHINA. And who will suffer? Definitely the people of Philippines. Thanks to him Philippines and other countries are still friends without conflict in anyone of them.
