There are other parallels. (All of the following is politically incorrect.) The so-called 'Jewish problem' a century ago was of the unassimilated millions in Eastern Europe exporting to the West bombers, fanatics, Communists. Rosa Luxemburg anyone? The West then found a "solution" that it tacitly approved, let's face it (because it didn't intervene, and now it throws the smoke screen blaming the Poles and the Ukrainians.). Today, the problem is unassimilated millions in the West producing bombers, fanatics, if not Communists (and no artists, no thinkers, no leaders, this time.) Will the East now come to the rescue? Scary thought, ain't it?
The anarchists and communists of a century ago were highly assimilated. Old-fashioned Orthodox Jews of the shtetl were not anarchists and communists.
