I'm going with a Global EMP attack. Would set up the same way this pandemic does and the preparations needed to get ahead of one.
Kids and parents at home…stocked up on food, less likely to be stranded and cause even more chaos.
No one shuts down the world for a virus. Especially when they have a known treatment for it with recovery rates of 99% plus.
Whatever this is … it is not just a global financial reset or response to a virus.
