Think Norway 1940, with a few assymetrical attacks thrown into the mix. Think DF-21s with radiation enhanced warheads. How would DF-21s with radiation enhanced warheads make subsequent invasion worthless? For that matter, how would DF-21s, with other nuclear warheads of low yield (but ones perfectly capable of destroying an airfield, or, critical C4I) preclude invasion? Let's assume something even worse - big city busters applied to Taipei (but not Hsichu). Still, an invasion could proceed and the PRC still gets the gold. So what if a bunch of peasants die from rad poisoning 2 days after invasion? Do you think that the PLA is infested with diversity trainers, occupational health specialists and lawyers?

Because you're still destroying infrastructure needed to sustain the invasion force. The PLA's logistics are, to put it charitably, about as inept and divorced from the realities of combat as your proposed war plans are. The only way the ChiComs will be able to sustain their forces is to capture INTACT logistics infrastructure on Taiwan--which is unlikely in the extreme, especially if they're nuking it.

Also, there will be real consequences to the ChiComs. Remember that treaty between China and Russia that you like to crow about? It'll be dead and buried--probably under the ejecta from multiple Russian warheads landing on Beijing.

If the ChiComs are willing to use nukes on Taiwan, where ELSE might they be willing to use nukes? Vladivostock?
