I didn’t post the pics, others did. Maybe they have been scrubbed, but they did appear here.
Others here not only posted the photos. but named the exact location(s) in Syria to where they were transported. That information must still exist in FR archives in text form.
Then there’s the issue of Syria’s poison gas arsenal, which Putin claims to be destroying.
Where else did it come from?
You can make chlorine gas in your garage.
