The problem to your plan is the PKKThe best solution to all this mess is (and always was) to just not let any Syrian in Turkey and to seal the borders tight... Then to let Bashar and Putin deal with them the best way they can- with barrel bombs. <3
Retreating from Syria, under the current conditions, imply that the PKK will come back stronger than ever and will probably establish long-lasting radical shia communities in Syrian cities that were originally moderate sunnis
Such a shift in the demographics will have just the same catastrophic consequence on Turkey just like with the massive syrian refugees that aims to topple the Turkish demographic
Furthermore, with the US set on supporting the PKK in order to destabilise the region and hopefully partition oil-rich Turkish territory from the mainland regardless of the consequences as well as Turkish pleas; The only way rn is to make a deal with Assad and Russia to try and take them onto the anti-PKK side just like with Iraq
But will such a deal succeed when Assad family has deep connections with the PKK? And will the US remain silent? And even if Assad supported Turkish interests, does the Russian-Turkish alliance have the strength to kick zionist USA out? What about the Turkish economy and US retaliation and sanctions? And what about the Israeli-Kurdish corridor that will eventually be a reality when Israel invades Lebanon? And above all, will Iran remain silent?
The whole Middle East is on the verge of a massive all-out war and no one knows where this shit is going
