Vietnam will not let US fighter take off. I dont think Pinoy will, especailly if Duterte gang on power.No, US is rallying nearby countries and being friendly with them so they will allow them to station their military. my take is china US is gona bring so much weaponary in Japan, Phillipines, etc that china wont invade taiwan.
and this is basically what a cold war is
Singapore Malaysia Thailand Korea will politely refuse. They cant offend China.
Only Japan can be count on in this situation.
But Japan is too close. On the day US fighters take off from Futenma to intevene in Taiwan, the runway is going to have a big hole next second.
