I’ve heard that action alone triggers an advance from the CCP
More likely it triggers more lipservice but people havent been willing to risk it (nor has there been broad enough consensus in Taiwan to relinquish their own claims to the name and the mainland and the same other territorial expansionist policies that the CCP has, people seem to forget that)
Also, get nukes from the US and say that they will use first strike if they are threated by CCP.
