Weak Watercolors Caused World War II?

Do people still actually believe the Hitler-was-a-frustrated-artist theory of why the world suffered through a World War and the Holocaust?
Four years ago, the Williams College Museum of Art suggested as much, in an exhibition that I reviewed for the WSJ on Hitler’s early years in Vienna. The fate of the world, as seen by the show’s curator, Deborah Rothschild, may have rested in the hands of one Christian Griepenkerl. He was director of painting at the art academy that denied Hitler admission.
“Perhaps if Griepenkerl had been a less rigid judge of exams, the entire history of the 20th century might have been different,” an exhibition label fatuously hypothesized. Never mind that Hitler was already showing signs of irrational fanaticism and anti-Semitism during those formative years.
Flash forward to the story in yesterday’s Guardian of London, which quotes Ian Morris, auctions manager for Jefferys, a British firm that in September will offer 21 mediocre watercolors, possibly from the hand of the nascent tyrant:
Perhaps if his art had been better received and he had developed a successful career as an artist rather than being rejected by the art establishment, he would not have become the man he did, ultimately responsible for the death of millions of people.
Perhaps Morris should restrict his critical faculties to his firm’s other merchandise, some of which he probably understands better than art or geopolitics: also coming in September at Jefferys, the much anticipated “Rare Breed Poultry and Collective Machinery Sale.”
