But why would an enemy nation want to make it easier economically for a nation they were against?
I think part of the intention was to increase the protection of the elderly that is a rock of our culture. To say they wanted to kill them off is to think only in terms of the biological capabilities of the virus. Possibly they wanted to provoke the further disparagement, beyond our usual ageism, of older people, which is what is happening in Sweden and among some people here. To create the disparagement of the people who have our culture most solidly in their heads and hearts.
It’s a cultural attack.
Same with the attack on the virility of young men. It would have made better sense to attack the fertility of women, in terms of population control—to decrease the general population. But attacking the virility of young men is a psychological attack. On our culture and subsequently on our military.
Maybe China was just the place where it was developed...
