We know that Ralph Baric at U of North Carolina at Chapel Hill worked on the virus. We also know the US military was in Wuhan for the Military World Games just before the outbreak.

What if China and the rest of the world blames Trump and the US military for releasing a bioweapon in Wuhan???
If you have followed, say, MKUltra you would know that these projects start in the US but when they get to the stage where they could be useful but need to be kept away from scrtiny they need to go undercover. The standard route is to move the research to Canada and into the private sector. (No FOIA and foreign country.)
The project's name is changed as well. That permits every bad actor in the US to say that, for instance, the MKUltra Project stopped years ago and the government is no longer involved.
George Webb was telling us about Foprt Detrick and this type of virus research quite a long time ago now.
Amazing Polly has just told us about Canada and links to CHina and other suspicious outbreaks.
