TW insurance is TSMC, if DPP allow its crown jewel to be taken over by the American (Arizona FABS) then its goodbye, will the American risk a WW3? You see China had declared its intention globally, TW is her core issue , she is willing to have a peaceful reunification and when provoke she is willing to fight and is preparing for one. And if TW is successfully invaded it will give China an extra strategic depth and may force the US in defensive to the second island chain therefore threatening Japan and the US bases. Now I ask you with all that posturing Japan is showing will she fight and die for Taiwan? knowing the possible retaliation which China will not hesitate as payback for all those crime Japan had committed during the SIno-Japanese war and WW2.Let's not discuss nuclear escalation because the outcome is definitely something neither side would want. However, I could see a coalition of US, UK, AUS, JPN, maybe CAN and IN attempt to take back TW by conventional means.
