How big would Germany be without the war and its pre-war (or even pre-World War 1) borders intact? How big would France be? Austria even. Or the myriad other mainland European countries which were occupied by the Third Reich?

Poland deserves representation in the EU parliament.
And how big would the United States be if it won the War of 1812, took over all of Mexico after the Mexican-American War, and Cuba and the Philippines became states some time after the Spanish-American War? Even had Congress accepted that crazy American who temporarily took over Nicaragua and tried to offer it to the United States.
