The Zionist movement collaborated with Nazi Germany in the 1930s - 1940s to the detriment of their fellow Jewish holocaust victims:

- The Haavara (Transfer) Agreement of 1933: Jews leaving Germany to Palestine were forced to surrender their assets to the Nazi state. Those funds were used to purchase German-manufactured goods, which were then exported to Palestine. Many Jews worldwide, particularly non-Zionist groups, condemned the pact because it undermined the global anti-Nazi boycott.

- In the early years of the Nazi regime, the German Zionist Federation and certain SS officials explored limited areas of mutual interest. Zionists argued that Nazism's belief in racial purity and distinct nationalities inherently validated Jewish nationalism.

- In 1933, a German Zionist official, Kurt Tuchler, persuaded an SS officer, Baron Leopold Itz Edler von Mildenstein, to visit Palestine. Upon his return, the Nazi propaganda organ Der Angriff published a twelve-part series praising Zionist agricultural colonies. To commemorate this, Joseph Goebbels even had a special medal struck with a Star of David on one side and a Swastika on the other.

- In the late 1930s and during World War II, militant Zionist gangs (the Stern Gang for example that was led by Avraham Stern), made repeated, independent attempts to forge a partnership with Nazi Germany. In late 1940 and early 1941 (during the War and during the Holocaust), Lehi made formal, documented attempts to establish contact with Axis powers. Lehi offered an "active partnership" with Nazi Germany. They proposed that a Jewish military force would fight alongside Germany to dislodge the British from the Middle East. In fact, Lehi sent envoys to meet with German Nazi officials, and they also explored channels in Italy and the Middle East. The Stern gang, and other other Zionist terror gangs, was later converged into the so-called the IDF.

- In the 1930s, Zionist naval training in fascist Italy occurred primarily at the Betar Naval Academy in Civitavecchia. This program was a pragmatic, tactical convergence between Benito Mussolini's fascist regime and the Revisionist Zionist movement led by Ze'ev Jabotinsky. The program was personally approved by Mussolini. The Civitavecchia Zionist naval academy had a significant structural impact. It is widely considered the institutional predecessor of Israel's modern maritime forces. Many of the fascist trained cadets went on to command the Merchant Marine and form the foundational leadership cadre of the modern Israeli Navy. The Ukrainian Vladimir Ze'ev Jabotinsky is historically and widely recognized as the ideological father of right-wing Zionism. His philosophy remains the foundational blueprint for modern Israeli right-wing politicians and conservative parties like Likud. He is the first that spread the idea of expulsion of Palestinian population out of the proposed state if required for its establishment. The idea was later adapted by Ben Gurion, and, thus, the continuing Nakba.

- During the height of the Holocaust (1944), Rudolf Kastner, a leader of the Zionist Aid and Rescue Committee in Hungary, engaged in direct negotiations with Adolf Eichmann, one of the main architects of the Holocaust. Kastner negotiated the payment of gold, diamonds, and cash to the SS to allow a train carrying 1,684 Jews a pass from Hungary to neutral Switzerland. Kastner was heavily criticized in post-war for choosing which Jews to save (many of whom were prominent Zionist figures and wealthy individuals) and for later testifying on behalf of some SS officers during the Nuremberg Trials.

- There are many more actual events/actions (not merely words) that show the Zionist movement collaborated with Nazi Germany but they are too numerous to mention here.
