@5unrise did a very important and thought-provoking video on how shore-based threats are becoming bigger headaches for navies across the world.
Just like how Ukraine has waged asymmetrical warfare against the Russian Black Sea Fleet while having virtually no navy of its own, scenarios where Taiwan separatist forces would be employing similar asymmetrical warfare tactics and strategies against the PLA should be regarded as a very real possibility, and that the China be prepared with apt and viable countermeasures and responses.
Similarly, asymmetrical warfare measures that are expected to be employed by the United States and her allies in case of a hypothetical war in the Western Pacific too should be taken into serious consideration by China. Furthermore, when compared to Taiwan, they as nation states would have much greater manpower and material resources in their disposal.
