Two words: biological lab(s).
Not in 1917.
If we view the latest Coronavirus from the perspective of five previous Chinese viral pandemics, then we begin to wonder if somebody in authority in China didn't, at some point, realize that China's capabilities for producing global pandemics might be a strategic national asset?
Suppose, for example, that China was more-or-less coerced into a trade deal which didn't kowtow enough to Chinese self importance, and China wanted out, but didn't want to break the deal themselves...
So China unleashes a global viral pandemic which destroys the world's economy and makes the trade deal impossible to comply with... ?
And President Trump, who is famous for speaking his mind, is most reluctant to say anything that might ruin the trade deal he worked to hard and effectively to achieve.
Until... until it's totally obvious the deal is broken anyway, and then, the Great Deal Maker will begin work on new deal.
I think that might be just where we're at right now.
It's why he's not afraid to call it "the Chinese virus".
I'm just saying, it's the sixth Chinese virus.
