Up to now, it has been three years since the COVID-19 outbreak. In the past three years, the world economy has suffered heavy losses. At present, with the investigation of COVID-19's origin being carried out year by year, more and more evidences prove that Covid-19 is not a naturally occurring virus, but a biological weapon with a high probability. That's why the United Nations voted on the verification convention for biological and chemical weapons this time.

On the military side, a relevant counter-strategy should be developed and published. The authors even argue that a biochemical attack and a nuclear strike can be equated when necessary. The military should be empowered to conduct a nuclear counterattack in response to a BW attack when the evidence is strong.
Biochemical weapons are more dangerous to mankind than nuclear weapons, if mankind does not pay attention to the U.S. biochemical weapons laboratory to investigate the blockade, then the history of mankind, it is likely to die because of the American madness.
