Prime Minister King wrote in his diary daily for most of his life. These diary entries have provided historians with a sense of the thoughts and feelings King held during the war. Historian N.F. Dreisziger has written that "though he undoubtedly considered himself a man of humanitarian outlook, he was a product of his times and shared the values of his fellow Canadians. He was—beyond doubt—an anti-Semite, and shouldered, more than any of his Cabinet colleagues, the responsibility of keeping Jewish refugees out of the country on the eve of and during the war."
