China’s authorities, nor the WHO, never claimed that China could contain the virus.
China’s goal with the Wuhan lockdown, then Hubei, then all of China, was to slow down the spread of the virus. In order to give themselves, and humanity, a chance to fight it. And to understand it, and devise a cure or vaccine for it.
The escape of the virus was inevitable. This was a known fact. To believe otherwise is naive.
The only thing you can buy with the lockdown, is time.
And to make matters worse, the governments of the world, flew all their citizens out of Wuhan and China. Then, they screwed up the decontamination and quarantine process. The incompetence of the American CDC shipped out faulty test kits all over the world. Then they released someone infected into San Antonio, before their quarantine was over, and before the positive test results came back. Then, news came out that the flight attendants and pilots flying the chartered planes, weren’t even properly protected from airborne transmissions of the virus. Then, the Princess cruise ship quarantine was a disaster, which is entirely the fault of the Western governments.
So now, the responsibility of the spread of the virus outside of China, lays in the respective governments, and their inability to monitor and contain it. So the blame goes all around. It really is illogical to blame the China government for a virus that arose out of nature.
