Timothy Snyder outlines the findings put forward in his widely acclaimed book Bloodlands (2010). Snyder argues that Hitler's regime was responsible for more deaths than Stalin's, contrary to the thesis that had been widely held since WWII. Snyder's findings, based on research materials that only came to light after the end of the Cold War, have changed the way we view both regimes, and the history of the mid-twentieth century as a whole.

A classic. Not quite cutting edge historiography, but most amusing nonetheless!
