Okay, I&#x27;ll just quote parts of the declassified the document you linked to:<p>&quot;C. IF THE SITUATION UNRAVELS THERE IS THE POSSIBILITY OF ESTABLISHING A DECLARED OR UNDECLARED SALAFIST PRINCIPALITY IN EASTERN SYRIA (HASAKA AND DER ZOR), AND THIS IS EXACTLY WHAT THE SUPPORTING POWERS TO THE OPPOSITION WANT, IN ORDER TO ISOLATE THE SYRIAN REGIME, WHICH IS CONSIDERED THE STRATEGIC DEPTH OF THE SHiA EXPANSION (IRAQ AND IRAN).&quot;<p>So a Salafist principality is exactly what the supporters (US, Turkey, Saudi Arabia) of the opposition want.
