Explain hitler's strategy of attacking the soviet union. why did his delay in launching the attack ultimately con- tribute to the soviet victory over the germans?

Hitler did not take into consideration the prevailing weather and climatic landscape of soviet Russia.

He attacked on winter and the rest of history. Russians retreated from the cities, often with a scorch Earth policy, and of the German forces that entered Russia: cold and hunger destroyed over 70% of the forces.

Only a handful reached Poland. The soviets red army then striked back.
