The pandemic taught us all that globalisation weakens us and makes us vulnerable to such plagues because joined up nations linked by airports governed by economy of market forces provides a bridge for plagues to spread fast and wide.

Let us not make it all about hatred of foreign nations, though, lest war replace pandemic.
