“During my youth I rather leaned toward the prognosis that the Jews of different countries would be assimilated and that the Jewish question would thus disappear, as it were, automatically. The historical development of the last quarter of a century has  not confirmed this view. Decaying capitalism has everywhere swung over to an intensified nationalism, one aspect of which is anti-Semitism. The Jewish question has loomed largest in the most highly developed capitalist country of Europe, Germany. […]
The Jews of different countries have created their press and developed the Yiddish language as an instrument adapted to modern culture. One must therefore reckon with the fact that the Jewish nation will maintain itself for an entire epoch to come. […]
We must bear in mind that the Jewish people will exist a long time. The nation cannot normally exist without common territory. Zionism springs from this very idea. But the facts of every passing day demonstrate to us that Zionism is incapable of resolving the Jewish question. The conflict between the Jews and Arabs in Palestine acquires a more and more  tragic and more and more menacing character. I do not at all believe that the  Jewish question can be resolved within the framework of rotting capitalism and under the control of British imperialism. […]
Socialism will open the possibility of great migrations on the basis of the most developed technique and culture. It goes without saying that what is here involved is not compulsory displacements, that is, the creation of new ghettos for certain nationalities, but displacements freely consented to, or rather demanded, by certain nationalities or parts of nationalities. The dispersed Jews who would want to be reassembled in the same community will find a sufficiently extensive and rich spot under the sun. The same possibility will be opened for the Arabs, as for all other scattered nations. National topography will become a part of  the planned economy. This is the great historic perspective as I see it. To work for international Socialism means to work also for the solution of the Jewish question.”
