 With the general feeling that the Axis forces in Europe were nearing their defeat, the Irgun decided to shift its policy from cease-fire to an active campaign of violence, as long as it would not be hurting the war effort against the Nazi Germany.In the autumn of 1943, the Irgun approached Lehi and proposed jointly carrying out an insurrection.The Irgun was now led by Menachem Begin, who had headed Betar in Poland before arriving in Palestine with the Polish forces in exile and going underground.
