While all the "gedolim" of that era, pre-war and post war, said it is assur to go to EretzYisroel and America, Rabbi Shraga Feivel Mendlowitz zt"l flew the American and Israeli flags together at Camp Mesifta in 1948 after the UN proclaimed Israel a State!
Aaron Kotler was wrong, the Agudah was wrong, Satmar was wrong, Elchonon Wasserman was dead wrong! Among tens of others. That's when he sent Rabbi Alexander Linchner z"l, his son in-law, to Israel to "save the sephardic kids from secularism"
...He knew Zionism was imperfect, he chose to improve it rather than walk away from secular Jews. YEHI ZICHRO BARUCH!
