Oh my.
I guess if you are going to kill all your little girls you have to do something with the men. I wonder what their M/F ratio is at that group these days.
I have two minds on this.
It is weaponized to eliminate those of the enemy that might resist an invasion while the chicoms would theoretically be vaccinated.
It is weaponized to lower the population of all males. China has a lot of extra males of fighting age so she would still have enough to prosecute a war...
