“The supreme art of war is to subdue the enemy without fighting.” —Sun Tzu, The Art of War
Biological warfare, while it may kill the enemy, is generally designed to cause many casualties and disruption. Those surviving victims of the biological agents will need the attention of many other people and resources. Biological warfare may also cause panic and disruption of a region’s economy. These are some of the things I learned during my two years as an officer in the Army Chemical Corps where I was specifically trained in CBR: chemical, biological, and radiological warfare.
As the story goes, the Wuhan Institute of Virology in Wuhan, China, was conducting research on corona viruses when by accident (?) some of the virus escaped into the city and infected some of the citizens. China immediately quarantined the city and stopped travel within China. They could possibly have prevented spread of the virus if they had also stopped international travel and warned the world of what happened. But they didn’t. Perhaps the Chinese Communist authorities realized they had an opportunity destroy the economies of western countries. Because international travel was not immediately stopped, infected, asymptomatic people carried the virus around the world. China lied and people died. People and governments panicked.
It seems that the Chinese Communist authorities were paying attention to Sun Tzu.
Much of the panic was caused by computer models which predicted millions of deaths. These models were based on bad assumptions and insufficient data (very similar to climate models). For more on that subject, see: The Danger of Letting Lab Coats Run the World
