Taiwan has 2 nuclear power plants and enough technology to create a bomb or 3 in record time if need be, plus a delivery system that would easily put every major Chinese city in reach. China could easily overwhelm Taiwan but it could come at a terrible cost.
Sure, and they could take out the 3 Rivers Dam, maybe.
But then the ChiComs would go scorched earth extermination on Taiwan.
The ChiComs have 50 million “excess males” they would be happy to send on one-way trips for a good cause.
Nuke plants run on 5% enriched Uranium, I believe.
It has taken Iran a full program and years to get to 60%.
They need to get to 90% for a bomb. They can’t do that in weeks or months.
