While I was police commissioner, an anti-Semitic preacher from Berlin, Rector Ahlwardt, came over to New York to preach a crusade against the Jews. Many of the New York Jews were much excited and asked me to prevent him from speaking and not to give him police protection. This, I told them, was impossible; and if possible would have been undesirable because it would have made him a martyr. The proper thing to do was to make him ridiculous. Accordingly I detailed for his protection a Jew sergeant [sic.] and a score or two of Jew [sic.] policemen. He made his harangue against the Jews under the active protection of some forty policemen, every one of them a Jew! It was the most effective possible answer.

Justice and fair dealings among nations rest upon principles identical with those which control justice and fair dealing among the individuals of which nations are composed, with the vital exception that each nation must do its own part in international police work. If you get into trouble here, you can call for the police; but if Uncle Sam gets into trouble, he has got to be his own policeman, and I want to see him strong enough to encourage the peaceful aspirations of other people's in connection with us. I believe in national friendships and heartiest good-will to all nations; but national friendships, like those between men, must be founded on respect as well as on liking, on forbearance as well as upon trust. I should be heartily ashamed of any American who did not try to make the American government act as justly toward the other nations in international relations as he himself would act toward any individual in private relations. I should be heartily ashamed to see us wrong a weaker power, and I should hang my head forever if we tamely suffered wrong from a stronger power.

I don't think any President ever enjoyed himself more than I did. Moreover, I don't think any ex-President ever enjoyed himself more.
