Turkish Strategy In Northern Syria: Military Operations, Turkish-backed Groups And Idlib Issue.

The conclusion:

In the contemporary military and diplomatic reality surrounding the Syrian crisis, Ankara is pursuing the following tactical goals:

To eliminate or at least disarm and limit influence of US-backed Kurdish armed groups in northern Syria;

To strengthen a united pro-Turkish opposition Idlib and to eliminate any resistance to it, including in some scenarios the elimination of Hayat Tahrir al-Sham and its allies;

To facilitate return of refugees from Turkey to Syrian areas under its own control;

If these goals are achieved, Ankara will significantly increase its influence on the diplomatic settlement of the crisis and on the future of the post-war Syria.
