It is nice to know that these materials are harmless. We should bring them back as trophies of war and display them. (Outside the New York Times seems like a good spot.)
This would demonstrate how safe these "old, deteriorated" weapons are.
Here's Santorum's interview with Hugh Hewitt:
HH: Now of these 500 shells that they have recovered, Senator Santorum, does the document, the unclassified version, tell you in how many batches they were discovered? Was it one? Was it 50 of 100, or one of 500?
RS: You know, I can't talk about what additionally it tells you. All I can tell you is there have been published reports on blog sites about this report...and the published reports say that 75% of these 500 or so weapons were in fact FILLED and USABLE, and VERY DANGEROUS for the...if got to improper hands.
I'm afraid i think it's too early to get excited about this. Only one page of the report has been declassified by Negroponte, and that doesn't give us anything to base our case for invading on.
