On NPR the other day they were talking about this find--it seems the Polish government wants to play up the find and the U.S. government wants to downplay it. So perhaps there is something that can be accepted as the "truth" somewhere in the middle. These are apparently old weapons left over from the Iran/Iraq war. Viability (odd term, though, to consider a killing agent "viable," eh?) is a factor. Is it or isn't it [viable]?
