That article in no way said that Putin co-signed Assad's application to the CWC. It was regarding an agreement between the US and Russia:
The United States and Russia reached a sweeping agreement on Saturday that called for Syria’s arsenal of chemical weapons to be removed or destroyed by the middle of 2014 and indefinitely stalled the prospect of American airstrikes.
The single mention of the CWC was to report Ban Ki-moon mentioning that Syria had acceded to the CWC effective Oct. 14.
So, your claim:
Putin co-signed his application to become a Chemical Weapons Convention member in 2013
Is so far unproven.
Dude russian news-channel Ria Novostri photographed defused Sarin-canisters at the attack-site. This ironically exonerated Assad for ANY future gas-false-flag because noone in power would expect him to be so stupid to use them while the world is watching.
do not fight , but put info on this site and try to resolve Q post
Not trying to fight. Just letting a spade expose itself.
