Hitler’s main goal in attacking Russia was to keep the war on only the western front. Russia was the eastern front and Hitler realized that if he ended up fighting on both the eastern and western front he would not be able to it and he would lose the war. When Hitler invaded Russia he thought that it would be an easy win and that they would be out and defeated very quickly but he underestimated Russia and the effects of a winter in Russia. When Hitler invaded the war was not as easy and he had determined. The war also went longer than expected and so Germany’s supplies were stretched farther than they should have been. They also underestimated Russia’s abilities.          This attack on Russia ended up turning into a major disaster for Germany. Russia’s winters are long, cold, and hard and Germany was not prepared mentally or physically. Germany believed it would be an easy fight until the winter hit them hard. This was a complete disaster for them because they lost so many people and this attack on Russia ended up leading to the Germany defeat in the war.
