The most profound effect of World War I on me ... was that it committed me to international affairs as the principal work of my life. ...I have sometimes regretted that my avocation or chief hobby happened to be such a gloomy one. ...When I look at the world today ... I sometimes wonder whether [my efforts] were not nearly all in vain. Perhaps it would have been better if I had adopted as my chief hobby the cultivation of chrysanthemums or the breeding of West Highland White Terriers or even, as did one of my friends, the collection of Japanese swordguards.
