The extermination of 6 million Jews by nazi Germany called for an urgently needed existence of Israel.
By the way, living (studying & working) in Germany (federal republic until 1989) between 1982 & 1993 I became aware that nazis & their descendants who fled after WWII e.g. to South America came back soon (with the pretext to deter communism) rebuilding an elite which didn't relinquish antisemitism nor anti Americanism.
