Jews and Nazis being in business relationships is not a new phenomena. In fact, Zionist Jews made a deal with Hitler to relocate to Palestine any German Jew who wanted to go there. Hitler bankrolled the creation of a Jewish presence in Palestine, later to become the state of Israel. He sold, leased and financed farming equipment for the settlers. He paid for their transport. It was called the transfer agreement.
