What if the coronavirus was a bioweapon designed to be used during a world war? Imagine if China was developing this virus with the purpose of using it in the event of a world war.

If a third world war were to occur then citizens would be blocked from traveling and the citizen would be landlocked. During such an occurrence China would be capable of doing a proper pre-release quarantine, but the enemies would not. The fact that the incubation time is anywhere from 2-30 days speaks volumes. It would be a weapon capable of infecting the enemy and go under the radar for as long as possible.

Such a weapon would be immensely powerful. So what if someone, on purpose, got infected? Premature infection, spreading the disease? That would render the weapon less effective as it wouldn't necessarily be dangerous enough while at the same time alerting other countries to the danger China poses.

I think the coronavirus was made by China, but got accidentally released through an "innocent" third party.
