So do you believe those civilians were killed by poison gas from Syrian Government or was it propaganda devised as a smokescreen for Western aggression against a poor, mus-understood Russia?
I want evidence the video is actually real.
In 2016 Amnesty International bluntly stated, "Syria: armed opposition group committing war crimes in Aleppo - new evidence. The Aleppo Conquest armed groups may have used chemical weapons, as well as ‘hell cannon’ gas canister munitions."
Russia says that the video was faked and they blame the UK and our proxy rebel forces. The US and UK have a track record of lying through their teeth about chemical weapons (e.g. Iraq) and and the US routinely makes up wild, moralistic propaganda claims (e.g. Nurse Nayirah), so it's clear no one should believe them.
At this point no reasonable, thinking person should be sure of anything.
Syria and Russia are demanding that independent, third-party investigators be sent to investigate the site and chemical weapons claims. The US refused, at one time falsely claimed that Russia was refusing the inspectors (they may have backtracked from that position by now), and either way, Trump's illegal attacks on Syria render that position moot.
The chemical weapons treaty mandates protocols and procedures when someone claims a chemical attack. Like it or not, Russia is following that. Currently, the independent, third-party experts from the OPCW are on the scene in Syria.
My guess is that in a week or so they'll issue a finding that there is no evidence of an attack and US/NATO mass media will ridicule the findings, scream cover-up, and then bury the story. Let's hope I'm wrong.
