During World War II, Cicognani expressed reservations about Zionism. In a letter dated 22 June 1943 to American representative Myron C. Taylor, he said: "It is true that at one time Palestine was inhabited by the Hebrew Race, but there is no axiom in history to substantiate the necessity of a people returning to a country they left nineteen centuries before …… If a 'Hebrew Home' is desired, it would not be too difficult to find a more fitting territory than Palestine. With an increase in the Jewish population there, grave, new international problems would arise."
