Evolution of US approach: Alleged attack – ̶I̶n̶v̶e̶s̶t̶i̶g̶a̶t̶i̶o̶n̶ – Retaliation (Video)

Washington has ignored warnings from Russia that the self-styled Syrian rescue group the White Helmets are directly involved in staging the attack, saying there is no evidence to support that claim.

And as the battle for Idlib province looms, the US is pouring troops into Syria – saying that, if there is a chemical attack, there will be a much stronger response than before.
