Ok, I should have been more specific: the way it is often framed (and the way I have seen it framed, and how the linked article frames it) is as if these were US-affiliated labs working on bioweapons. That is not what Nuland said. Biological research facilities do not have to be bioweapons labs, just as explosives research facilities need not be arms manufacturers.
Greenwald (the author of the linked article) of course does what Greenwald recently is hell-bent on doing, which is to try to scandalize anything he can. I used to respect the man, but that was a long while ago.
