When China moves on Taiwan, expect Russia to move on the Ukraine, North Korea to set off more missiles and nuke tests and Iran to put its proxy war on Saudi Arabia and Israel into hyperdrive.
A weak US leader creates a vacuum. It WILL be filled.
That is exactly what I think too, all at once. Kerry will be negotiating and accept an Iranian invitation to step outside and watch the first missiles launch. China might move on the Philippines and Japan too.
