In response to an alleged chemical weapons attack in the Syrian town of Douma which cost many innocent lives, Britain joined France and the United States in aerial strikes against three of the regime’s chemical weapons facilities. It seems clear the targets were destroyed, and that no lives were lost on either side. Inspectors from the Organisation for the Prohibition of Chemical Weapons were finally allowed into Douma this week but the evidence suggests that the Bashar al-Assad regime is guilty of a major war crime against its own people, by no means the first.
