On Wednesday the 22nd a new speech of ISIS chief Abu Bakr al-Baghdadi was published. A new video of HTS chief Abu Mohammad al-Jolani showed him rallying his forces. Joining the Islamists chorus of the day Abu Jihad John Bolton warned that any use of chemical weapons by the Syrian government would be responded to with force….This was obviously an invitation to the terrorists to stage a fake chemical weapon attack as they had done earlier in east-Ghouta and other places. Those incidences were blamed on the Syrian government without any evidence and led to U.S. strikes on Syrian forces.
