Another incident was the attempt by Yair and his associates to forge ties with Nazi Germany at the height of World War II. In early 1941, it became clear from information coming from Europe and published in the press that the situation of the Jews in Europe, much of which was occupied by Nazi Germany, was especially critical. Their rights were violated, they were fired from their jobs, their property was confiscated, they were evicted from their homes, they were imprisoned in ghettos and they had to put on yellow stars. But there still was not a feeling of impending doom. In fact, the Final Solution was a decision reached only at the Wannsee Conference in early 1942.
Yair believed that after Hitler captured Poland, he would want to banish the Jews from it, but he would not know what to do with them: to imprison them in ghettoes or transfer them to Madagascar. “We must speak with the Germans,” he would say time and again. He continued, “It is clear that if we cannot reach an accord with the Germans, the Jews of Europe will be exterminated! We must analyze the problem clearly: who are our enemies? What good is the war to us, and whom is it worth it to fight for the liberation of our land, for the salvation of our land, for the salvation of the million in Europe? It is clear to me:, the enemy is Britain. Saving millions was within its grasp, but she did not do it! On the contrary, she is interested in their extermination, so that she may preserve the Arab dominion in the land, which is the British dominion. There is not much worth to our helping the Allies. What good does it do us? Less than zero. That is why the only option left is for us to reach an agreement with Germans, to save the Jews of Europe by transferring them to Eretz Israel. Germany will do this in exchange for our war with the British. We cannot declare war against Germany while the Jewish people is prisoner in German hands.”
