The power of the Jews even today, especially in America, should not be underestimated. And therefore I have very deliberately and very consciously – and that was always my opinion – put all my strengh, the best I could, to bring about a reconciliation between the Jewish people and the German people.
— Dec. 29 1965, Konrad Adenauer.
It's surprisingly common. Arthur Balfour, who issued the Balfour Declaration that said Britain would support the establishment of a Jewish state in Palestine, did so in part because he believed jews were very powerful and it would be dangerous not to. Basically the entire British foreign ministry at the time were anti-semites who believed that "the all-powerful jew" would destroy them unless they supported zionism.
