The problem is, ROC has already failed. It is essentially a local separatist regime. Although its name is "Republic of China", it cannot represent China. To barely maintain this lifeless shell only creates space for those attempting to separate this territory from China, which is completely unacceptable to the Chinese people. So the situation is, either become a clearly defined province of China, or choose the war.
I do not believe that separatism holds any justification here. The authorities on an island with a 97% Han Chinese population are pushing a de-Sinicization(去中国化) policy, attempting to make its people no longer identify as Chinese. There is extensive hate-mobilization—some even use the term "Shina(支那)," a derogatory label for Chinese during Japan’s war of aggression, to refer to mainland China. This single detail reveals the utter lack of justice in their cause. I describe this as a lingering outpost of World War II-era Japanese imperialism in today’s world. It is utterly evil, and I see no possibility of peacefully maintaining the so-called "status quo" if this continues.
