Hitler wanted unification of the German peoples and was sympathetic to the British, while already Communist, Hitler still wanted to achieve Leibensraum in Eastern Europe. Hitler also wanted control of the rest of mainland Europe. He coerced the French Government into the signing of the Nice Treaty. When Italy refused to join the EU he forged an alliance with Stalin, though it was for convenience, Hitler was assassinated in 1938 and Stalin took control of the EU. Soviet ideology was a sharp contrast to that of the Confederates and so a war commenced until the annihilation of Europe through nuclear technologies in 1945.
