This article has nailed it. Taiwan's main threat is not from China's military. The US-led military alliance around China provides a strong deterrence to any of China's attempt to invade Taiwan.
On the other hand, Taiwan needs to pay special attention to the trojan horses planted by China on the Taiwanese island. These China collaborators, although small in numbers, could cause major damages to the Taiwanese resistance in case a war erupts, with disinformation and sabotages. These Chinese agents are mostly among KMT members and people with close business ties with China.
