What effects did being treated for blindness have on Hitler?
Terribly. There were forced to sign a treaty that basically stated that the whole war was Germany's fault. They had to pay a lot of money to the European nations. When they surrendered, Hitler was in the hospital being treated for a gas attack. When he heard this, he became irate, and so began the rise of Hitler...
The reasons for Mussolini allying with Hitler was that he could see that Hitler was going to start a war and probily take over the world and he did not want to miss out on the rewards of being on the winning side. The effects it had on Mussolini was that he was veiwed very highly around the world for re-stabilising the Italian govenment so allying with Hiler decreased his popularity with other world leaders
