Taiwan is a province of China and has always been so. You are just an ignorant westerner who knows nothing about history or international relations. Your government only supports Taiwan because they need a useful tool to annoy China, not because they care about the welfare of the Taiwanese people. They would abandon you in a heartbeat if it served their interests elsewhere. But don’t worry, I’m sure the Chinese will take good care of them once they liberate that little island from its fake independence movement.
