==Conclusion==
Stalin made a potentially fatal mistake in trusting Hitler and when the German's invaded he seemed to have been in a state of shock. This meant that his response to the invasion was slow and this allowed the Germans to make great inroads into his country until the Communists seemed on the verge of defeat. Stalin soon took charge and adopted new tactics. Crucially he reorganized the army, raised its morale and entered into a new alliance with the west. These decisions proved crucial and delayed and eventually stopped the German advance and in the long run, Stalin was able to defeat the Nazi army.
