It's even scarier than you think. A few years back I read an account of their germ warfare development program, which was worse even than what Mengele did for the Nazis. They were systematically and scientifically testing various weaponised diseases on "dissidents" and their children.
Do we think that they aren't now muking about with GM? If they started a war that they couldn't win, would they then hesitate to unleash whatever germs they have developed onto the world?
