Zionism
As a result of the Holocaust Teichtal changed his position on Israel as he struggled to make meaning out of what was happening around him. His carefully constructed arguments are outlined in his book Eim Habanim Semeichah penned during his wanderings in hiding from his Nazi oppressors and their collaborators. In that work, first published in 1943, he makes a case for the rebuilding of the land of Israel bringing about the ultimate redemption. In this respect his work had a precursor in the works of Rabbi Abraham Isaac Kook. His original view had been that of the majority in the Orthodox Jewish world at the time, which discouraged an active movement for a return of Jews to Israel. The prevalent view at that time was that God would bring about a return without the need of human mechanizations. The Holocaust caused him to re-think this approach, and he therefore came to the conclusion that the reason that the Jewish people had not been redeemed, was because they had not returned to their homeland, the land of Israel, to resettle and rebuild it to its former glory.
