Not likely. There’s no reason this stuff can’t be purely Syrian. Or for that matter Chinese or Russian.
Syria had its own, unmonitored chemical weapons program.
And 10 years of degradation (at least) of Iraqi chemical stockpiles is a serious factor. Most of this stuff just doesn’t keep very well.
So if you spray 10 year old sarin on people, they don't die?
This is good news.
We can safely shut down Anniston, Pine Bluff, Tooele and Umatilla!
Think of all the ObamaPhones the savings will buy!
“Most of this stuff just doesn’t keep very well.”
I don’t know, there’s an Army chemical weapons depot about 25 miles from my home, and some of the stuff stored has been there for sixty years. In fact, last year I interviewed for a technical writing job on the program to destroy the stockpile.
