I’d say 1,2 and 3. To make depopulation work they have to get everyone vaxxed in a hurry before folks figure out what is happening. Once they get rid of the “control group” they can blame the excess deaths on anything.

They would all be dead in 12 months. But that does not mean they wouldn't try it.
