Likely Reasons for German Jewish Cooperation in Regards to Palestine
"There was a "collaboration" between the German National Socialists and some Zionists, but let´s check out the situation:
In 1933, when the National Socialists ruled over Germany, they promote the Jewish immigration into Palestine via the so-called "Haavara agreement". The Haavara agreement, which was signed between NS Germany and Zionist groups after three months negotiations in 1933, is used as "proof" that the German National Socialists were Zionists in service of the Zionist agenda and that Adolf Hitler was the "founder of Israel". There are several factors which draw this accusation into doubt.
First, after the German National Socialists gained the power over Germany, the world Jewry declared war on Germany on 24 March 1933 by launching an international boycott on German goods. Germany already suffered by the great depression in 1929 (which BTW helped the NSDAP to gain more votes) and an international boycott on German good would damage Germany much more. The Haavara agreement wasn't just a deal to promote the Jewish emigration into Palestine, it was also an economical deal to break the international Jewish boycott.
Only a small fraction of Jewry supported Zionism, while the majority of Jewry didn't and wanted to destroy NS Germany. The Zionists used this situation and helped to break the international Jewish boycott in exchange for the emigration of German Jews into Palestine, therefore this "Haavara agreement" could be considered as a "blackmail", a win-win situation. Not all Zionists supported the Haavara agreement, some Zionist leaders such as Vladimir Jabotinsky rejected this agreement and favored over the international Jewish boycott on German goods. As a result of the rejection, the Zionist leader and head of the Jewish agency, Haim Arlosoroff who negotiated with the German government about the Haavara agreement, was assassinated by elements of the Zionist faction led by Vladimir Jabotinsky two days after his return from NS Germany.
Although the National Socialists wanted to complete the final solution of the Jewish question, which was the plan to re-locate Jewry out of Europe, they didn't want to allow a large number of German Jews to flee to other countries because they feared that these Jewish immigrants would lend large numbers to a growing international movement for the international boycott of NS Germany. Also, the German government saw Palestine, which was a British controlled area, as "dumping-ground" suitable to isolate a great number of Jewish refugees from the world's political arena.
Therefore the Haavara agreement was a strategical step for the German government, although the Zionists benefited from this as well and German "support" of Zionism had nothing to do with the plan to help to create a powerful Jewish state. In "Die Spur des Juden im Wandel der Zeit" written in late 1919 and published in 1920, Alfred Rosenberg concluded: "Zionism must be vigorously supported in order to encourage a significant number of German Jews to leave for Palestine or other destination." Alfred Rosenberg's early support for Zionism was for a more legal way to remove the Jews from Germany and he believed that Jews aren't able to create a Jewish state. Later, he advocated for the relocation of up to 15 million Jews on the Island of Madagascar which was the official plan of NS Germany (Madagascar Plan) for the final solution of the Jewish question and the establishment of a Jewish reservation:
"Non-Jewish observers and writers on Zionism, who see political Zionism only as an attempt at “national renewal” rather than an effort to establish a unified Jewish leadership as well as Jewish rule over the world, are therefore incorrect. The confusion of political Zionism with Palestine can be understood only through the Jewish prophecies in which Jewry is assured of control over all the goods of this world. Knowing that the time was near, and would culminate in taking possession of Palestine, Zionism developed the nonsensical notion of an "historic claim" to the "promised land," to which Jews "without any outside pressure" would gradually emigrate.
In the ideology of political Zionism, Palestine fulfilled the role of an indispensable part of prophecy, just as certain rules are the guarantee for success in the magical ceremonies of primitive peoples. Political Zionism never intended Palestine to be the destination of all Jews, but rather it merely wants to make Palestine the center of Jewish world policy. That must naturally be protected by a strong Jewish population. The Zionist publication Jüdische Rundschau wrote: "No one at any time has proposed that all Jews today should emigrate to Palestine." Nahum Sokolow, Weizmann’s colleague and current chairman of the Zionist Committee, said it clearly in 1921: "The Jewish people wants to return to Palestine; the Jewish people will have its center in Palestine. Large parts of Jewry will live as a Jewish periphery in the world. They must be cared for; their dignity and their national rights must be assured." [...]
That provides a correction to the idealization of Zionism, which springs from a different race. From a political standpoint, it would be in the interests of the whole world, of all the host peoples, if the Jews now scattered throughout the whole world were to voluntarily emigrate to some habitable territory. If political Zionism were not interested in such a solution to the Jewish Question, it would be in the interests of the host peoples to point it in that positive direction. The only question would be whether Palestine is the proper gathering place, which no one would likely maintain. Palestine is not able to absorb all the Jews in the world, entirely aside from the fact of increasing Arab opposition to Jewish infiltration. The Arabs are, after all, the undisputed owners of the land. But what other territory would be appropriate? And at the instant Palestine ceased to be the goal of Jewish emigration, political Zionism would collapse, since Palestine is seen as a means for the fulfillment of prophecy. Without that, the whole enterprise would lose its point. Jewry itself would make the most passionate and bitter attacks, and before long any undertaking that ignored Palestine would be crippled by Jewry itself. Palestine incorporates for Jewry its special position. Ignoring this would be ethnic suicide for Jewry, since political Zionism also has as a goal maintaining and strengthening Jewry’s special situation."
The Jewish professor Jeffrey Herf confirmed in his book "The Jewish Enemy: Nazi Propaganda During World War II and the Holocaust" that the National Socialists considered Zionism as a part of a Jewish conspiracy:
"In the Nazi view, Zionism remained in the context of a conspiracy. Hitler himself presented an early version of this view in Mein Kampf, when he contemptuously rejected the “lie” that Zionism was primarily a movement focused on creation of a homeland for the Jews in Palestine. “For while the Zionists try to make the rest of the world believe that the national consciousness of the Jew finds its satisfaction in the creation of a Palestinian state, the Jews again slyly dupe the dumb Goyim. It doesn’t even enter their heads to build up a Jewish state in Palestine for the purpose of living there; all they want is a central organization for their international world swindle, endowed with its own sovereign rights and removed from the intervention of other states: a haven for convicted scoundrels and a university for budding crooks.” For Hitler and the Nazi regime, Jewish immigration to Palestine could never be part of a “solution,” final or otherwise, to “the Jewish question” in Europe. Nazi opposition to a Jewish state was rooted in the core ideological conviction that a Jewish state in Palestine would become a component, or perhaps the very headquarters, of "international Jewry’s" efforts to dominate the globe.
Alfred Rosenberg, though also convinced of the existence of a Jewish conspiracy, showed less alarm about Zionism in his essays of the 1920s and 1930s than Hitler did. Rosenberg’s key text on the subject was Der Staatsfeindliche Zionismus (Zionism hostile to the state), which he initially published in 1921 and which the main Nazi publishing house brought out again in 1938. In it he argued that the Jews were incapable of statecraft. If a Jewish state in Palestine were to be established, it would collapse and again the Jews would become an "international nation." Zionism was "the ineffectual effort of an incapable people to engage in productive activity. Mostly it was a means for ambitious speculators to establish a new arena for receiving usurious interest on a global scale." In the midst of WWII, Hitler’s view that a Jewish state would provide another base for the international Jewish conspiracy displaced Rosenberg’s contempuous dismissal and fostered a convergence of anti-Semitism and anti-Zionism.
Giselher Wirsing’s Engländer, Juden, Araber in Palästina (The English, the Jews and the Arabs in Palestine), published in 1939 … defined the Zionist goal as the "establishment of a Vatican of world Jewry. A firm base is to be built on which in later years Jewish world policy can rest." Wirsing argued that a Jewish state would foster cooperation between the Jews in Palestine and the assimilated Jews who worked in finance and banking in Western Europe and the United States, thereby strengthening their existing political and economic power."
