Can there be any remaining doubt about the involvement of Iraq? Or, perhaps by proxy, China? They, along with the US, Britain, and Russia are the only people with the facilities to mass-produce weapons-grade anthrax; ergo, their involvement is nearly assured. I would hope that it's only a matter of hours before every Iraqi facility that has denied UN inspector access in the last five years is reduced to rubble.
And, is it just me, or does this seem like a bad time for GW to be in Beijing?
Anything that Russia has is for sale. I think it's a pretty scary situation for them to have all of that technology with such massive corruption. At any rate, I think that it's most likely Iraq.
