Singapore and Ireland will suffer badly as global trade declines and deglobalization proceeds.

The global economy will fracture because no nation is willing to take on the cost of being the global reserve currency; no one will replace America.

The age of globalization is over, and Chinese students studying in the US for a degree and a job back home will end.
