Shaw's final political treatise, "Everybody's Political What's What", was published in 1944. Holroyd describes this as "a rambling narrative ... that repeats ideas he had given better elsewhere and then repeats itself". The book sold well—85,000 copies by the end of the year. After Hitler's suicide in May 1945, Shaw approved of the formal condolences offered by the Irish Taoiseach, Éamon de Valera, at the German embassy in Dublin. Shaw disapproved of the postwar trials of the defeated German leaders, as an act of self-righteousness: "We are all potential criminals".
