Most migrants weren't Syrians, btw. But more importantly, I wish to remind you that when this mass migration was inflicted on Europe, the Left was very much in favor of this shitshow. There was no "dealing with the Syrian crisis" then (whatever anyone means by that). Nor was there any acknowledgement that the majority of migrants weren't fleeing Syrians. Syrians should have been helped on the ground in Syria, but only a few states seemed to promote that approach (Poland comes to mind).
All of this should suggest that the mass migration was weaponized.
