I can do this all day gents.
https://www.npr.org/sections/thetwo-way/2014/10/15/356360949/pentagon-reportedly-hushed-up-chemical-weapons-finds-in-iraqFact is. They were supposed to dispose of these.
"From 2004 to 2011, American and American-trained Iraqi troops repeatedly encountered, and on at least six occasions were wounded by, chemical weapons remaining from years earlier in Saddam Hussein's rule.
"In all, American troops secretly reported finding roughly 5,000 chemical warheads, shells or aviation bombs, according to interviews with dozens of participants, Iraqi and American officials, and heavily redacted intelligence documents obtained under the Freedom of Information Act."
If they had anything tangible about actual WMD's, do you really think the Pentagon would of kept it secret?
Or do you think they would of avoided the humiliation of no WMD's found by the U.S. in Iraq.
If they had anything in a favorable light they would of bragged about it to no end, justifying the invasion.
Now you are claiming remnants, that were supposed to be disposed of.
There was a Chemical weapons munitions plant in Vermilion County Indiana that stored VX nerve gas for decades and they didn't even get the funding to dispose of it until the mid 2000s, and it wasn't disposed of until 2008.
There was enough never gas in the Newport munitions plant that if it were released and the wind was going the right direction it could of killed all of Chicagoland.
