Taiwan definitely needs the support from the US, Japan and Australia in case of a Chinese attack. But its best defense would be to turn itself into a porcupine. To that end, a more distributed, mainly light arms defense would inflict maximum pains to the landed Chinese forces, yet is hard for China to destroy. The battle-proven Javelins and Stingers should be supplied to Taiwan in huge quantities.
