Try a different question:

How difficult would it be for *any* nation with a Bio-Safety Level 4 lab, not to engineer a terrifying synthetic virus, but to grow terrifying viruses from other species in human tissue in an attempt to get *Natural Selection* to develop the new strain. https://twitter.com/austen/status/1249414815740604416
I’m not a virologist versed in bio-warfare so I’ll take my answer off the air.
My next questions, however, would be:

A) To rank the nations most likely to do this.

B) To rank the nations most likely to have a failure in protocol leading to an accidental escape.

C) To rank the locations of the BSL-4 labs in those countries by accident likelihood.
