I've always felt that the test of WMD should be "could they, even theoretically, be used to kill large numbers of peopls?" In this case, the answer is no. There were only two shells that contained the cyclosarin (though the Poles initially claimed 17) and the material itself was at least fifteen years old, beyond its shelf life. The Polish defense minister said right off the bat that the warheads were not usable, but a possible danger to the local environment. The US Army confirmed that they were not usable warheads. We have been over this on another thread already, by the way!
