Mao was an utter failure, and incompetent to boot. Not a "great" leader in any way.
He was "great" at crazy scams schemes that killed millions though
He had that certain flair for sloganeering, too: "Great Leap Forward", "Let A Thousand Flowers Bloom" "Cultural Revolution"...
But none of Mao's measured up to the Imperial Japanese, though: When they raped Nanking, it was "East Asia for the Asiatics!" After they invaded the Dutch East Indies and the Phillippines, they made sure to set up a "Greater East Asia Co Prosperity Sphere" Those humanitarians.
