Stalin was the greatest leader in Human history. He turned the Soviet Union from a war torn, impoverished and backward nation into the most powerful country in the world. In it's hayday, the USSR was the largest academic power in the planet (producing more academic literature and more patents than any other country on the face of the Earth). It had the most powerful military, the best athletes, the best space program, and the best chess players! The USSR was the first fully literate country in the planet. The first country where minorities were constitutionally protected, and where women were allowed to pursue a career and education the same way men were. The USSR was the largest manufacturer on the planet, second largest economy on the planet, and had an incredibly low level of inequality. It also surpassed many Western countries in demographic indicators, such as death rate, and life expectancy. Peter the Great on the other hand, did relatively little. After killing hundreds of thousands of people to make St. Petersburg, nothing really changed for the majority of people. Peasants remained peasants, nobility remained nobility (albeit with less facial hair LOL). Russia on the whole remained poor and backward. People make various claims that Stalin had killed "millions" of people, but these quotes are mostly from the likes of Solzhenitsyn and other people who are equally unqualified to state such facts.
