The Grayzone OPCW whistleblowers have exposed a cover-up, under US pressure, of evidence that undermined allegations that the Syrian government committed a chemical weapons attack in Douma in April 2018. The allegation prompted US-led airstrikes on Syria that same month. Former Bush administration official Col. Lawrence Wilkerson says that reports of US pressure on the Douma investigation recall the Bush administration's coercion of the IAEA and OPCW before the Iraq war.
