Imagine. Taiwan is deeply divided between people in the north and the south. It has come to the point where there are two parties, the KMT and DPP, fighting each other. The KMT is still in power, but part of the army now supports the DPP. Violence erupts, civil war commences. The KMT loses the battle and defeated President Ma and his troops retreat to Orchid Island (Lanyu) where they are safe for the moment, cause the DPP has nothing left to take this now fortified island. Years pass and the situation is left unsolved. Lanyu develops quite nicely under KMT rule, though the indigenous population is less than happy, and there are even voices who call for an independent Lanyu. Now, the DPP on the main island always insists that Lanyu is an inseparable part of Taiwan and any declaration of independence would mean that the use of force to reclaim the island could not be ruled out.
One day a newly elected government invites an envoy from Mainland Taiwan two Orchid Island, but many Orchiders protest the visit because in their eyes the DPP people will always be the enemy…
Now, I know it’s not the same as the present situation, but what would be the difference, really? The same people demanding Taiwan Independence now would demand reunification with Orchid Island in that scenario. People on both sides aren’t that different, really.
