The notion that mass immigration from Syria to Europe is a necessary consequence of the war is trivially falsified by looking at the timeline. The Syrian civil war started in early 2011. Daesh entered the war in early 2012 as al-Nusra Front, and operated as ISIL since 2013. The Caliphate was proclaimed in summer 2014.<p>But mass migration into Europe did not start until summer 2015. Obviously it did not take the Syrians four years to realize that there was a war in their country.
