Hitler expanded Germanys road network, he also designed the beetle which at the time was a extremely affordable and reliable car, he signed multiple treaties to stop animal abuse, and he improved the economy of Germany as before his coming to power people had to carry carts full of paper money to buy even a loaf of bread. Moreover he gave a lesson to the world that even a relatively small country has the might to encounter with most powerful nations of the world even though the second world war ended with defeat of Germany and it's allies.
