The US empire always has to have an enemy, to justify funding the military-industrial-intelligence complex. China looks like its going to be the designated bad guy for quite some time. From Caitlin Johnstone at caitlinjohnstone.com:

“What we know is that the nation’s top intelligence official says that the US has evidence that China is conducting biological experiments on its soldiers to enhance their capabilities,” said CIA asset and reporter Ken Dilanian on a recent MSNBC segment designed to keep you nice and terrified of the west’s current Official Bad Guy.
“I was somewhat skeptical about this claim, but when I started poking around I found that private American military experts in the think tank world have actually studied this issue and written about it and they have found that there is ample evidence that Chinese scientists are very interested in applying bio-technology to the battlefield,” Dilanian continued. “Picture super strong commandos who can operate on three hours’ sleep, or a sniper who can see twice as far as a normal person. This is the kind of thing that the Chinese aspire to doing, and you know, it’s problematic because in the west we consider that to be unethical, to tamper with the genes of healthy people.”
