Latest estimates of The Great Helmsman's postwar follies indicate 100,000,000+ victims in that nation alone.
Add some of government's other shining excesses in the great century just passed, and the 170,000,000 figure is completely believable.
(Ever since such State-sponsored galas as Tianenmen Square and Waco, tanks are a symbol of crushing government power as much as they are of war.)
