Greenwald seems to be reading into her comment in an unsubstantiated way. I don't think you can call that a "confession."

Many countries have "biological research facilities." Militaries will, for defense research, but think of all the BSL-3 labs in universities. It's all inherently dual-use stuff.. there's legitimate reasons to study anthrax, but it also makes for a weapon.

What differentiates biological weapons stockpiles from research facilities is scale. Russia had massive amounts of anthrax in its Biopreparat facility. They claimed it was for research, but research doesn't require massive, industrial-scale incubators.

If Ukraine has those, they'll be found. If all Russia finds is a BSL-3 lab with a handful of petri dishes, that's nothing.
