By moving their most advanced fab factories 5 nm and then 3 nm again, TSMC is in died route one way, 死路一条.  

Gone case liao.

I think very likely too.

But once the Chinese companies overcome this handicap in the next 5-6 years thru their own R&D, TSMC US fabs will find it hard to compete.

Huawei's recently announced their patent on EUV mirror control (optical lens doesn't work for EUV light):
