To be clear, the concept of “the Taiwanese people” is a modern construction. It would be like saying the people of California are the only ones who can decide if California is part of the United States of America. The people of California are in fact Americans. And while they may have an opinion about their desire to participate in the federal government, the existence of California depends entirely on the United States government for its legal basis. Additionally the territory that makes up California is of incredible critical importance to the national defense and economic ability of the United States of America to provide for the livelihood of its citizens. The people of California have no greater claim to completely independent nationhood than the people of Taiwan.

But to be abundantly clear not only do I agree with you, that the people of Taiwan have the authority to make the vast majority of decisions about their self-governance - excluding those issues that threaten the self-governance of others - but the CPC also agrees with that position and has clearly stated that position for decades. It is the US and the collective West that continue to report their speculation that China will invade Taiwan and is preparing to invade Taiwan despite literally decades of official Chinese government positioning that it will not invade Taiwan unless the United States or another foreign military uses its relationship with Taiwan to threaten the rest of China.
