Dr. David Martin has laid this out succinctly, every i dotted and t crossed, in his discussions of this. Patents, timelines, emails, etc...
The University of North Carolina Chapel Hill <——>China back and forth is there.
I personally think that there was a possible underlying SpyvsSpy double-cross in action too. China was looking for a viral contagion to assail the west, but the “recipe” they received was for a pathogen that was far more problematic for Han Chinese than western European and African descent peoples (plus half or more of Africa is soaked in anthelmintics so CoVid was a “Huh?” there).
Thank you.
