> If Europe blocks its efforts to stabilize a part of Syria
It's not trying to do that, though that's the pretext. As with Turkey’s previous interventions in Syria and Iraq (and its ongoing internal campaigns), it's trying suppress the Kurds. If it's trying to create a pacified area, it's to avoid having a safe space for Kurds, not to repatriate Syrian refugees (except perhaps to repatriate non-Kurdish Syrian refugees to displace the Kurds, which is certainly a plausible Turkish strategic aim.)
