In 1940, Lehi proposed intervening in World War II on the side of Nazi Germany. It offered assistance in "evacuating"[vague] the Jews of Europe, in return for Germany's help in expelling Britain from Mandate Palestine. Late in 1940, Lehi representative Naftali Lubenchik was sent to Beirut where he met the German official Werner Otto von Hentig. Lubenchik told von Hentig that Lehi had not yet revealed its full power and that they were capable of organizing a whole range of anti-British operations.
On the assumption that the destruction of Britain was the Germans' top objective, the organization offered cooperation in the following terms: From the NMO side: full cooperation in sabotage, espionage and intelligence and up to wide military operations in the Middle East and in eastern Europe anywhere where the Irgun had Jewish cells, active and trained and in some places with weapons. From the German side, the following declarations and actions were demanded: (1) Full recognition of an independent Jewish state in Palestine/Eretz Israel (2) That the ability to emigrate to Palestine be conceded to all Jews, with no restriction of numbers, who, in leaving their homes in Europe, by their own will or because of government injunctions. For this purpose there was expressed a need to cancel any transfer plans of Jews to distant countries like Madagascar.
