So why would communist China want to create such a virus and when would they use it if not against Trump who was coming after them head on and winning?
...[why] if not against Trump...
Why indeed.
Think Chinese.
Think long game.
Not that long, LONGER!
Here's a possible PLAnned scenario:
When we are thoroughly sick and tired of the muzzle theater and have, as a people, pretty much resolved we won’t be tricked again, that is the time for China to unleash a very deadly virus that has initially mild symptoms after a long infectious period, followed by the the deadly phase.
The powers that be have cried wolf to an imaginary wolf loudly enough and long enough that when we stop listening, the real wolf can easily spread far and wide unimpeded.
Think of it as the Wuhan-two punch.
Expect China to be a black hole of data. Their pre-vaccinated population (they will patiently wait until they have developed an actual vaccine, and have an inventory large enough for at least their entire Han population) will ride out the storm largely unaffected, and they will then have a greater Lebensraum, a whole largely unpopulated planet all their own...
A whole world, complete with farms, factories, roads and bridges, and empty homes.
Better than a neutron bomb, as it's everywhere, not just a few select targets!
