Idleb is still under control of the al-Qaeda aligned Hayat Tahrir al Shams (HTS) which has continued to attack Syrian government positions, as well as civilian targets. HTS is internationally recognized as a terrorist organization, including by Turkey. But Turkey has done nothing to remove it. It instead provides the organization with weapons and other supplies.
Turkey has all along operated in bad faith against Syria.
Although Turkey complains at having so many Syrian people in Turkey, if they had not been one of the initiating aggressor parties, the outpouring of Syrian people, would not have happened.
Perhaps we should look deeper for the real reasons for the Syrian “Civil” War?
