Through 1942, Hitler clung to a belief that Britain might make a separate peace, driven by fears that American hegemony threatened the British Empire. It was obvious that Germany's best, if not only, hope lay in finishing off Russia. A marginal measure of the cost of that vast struggle: in addition to human casualties on the Eastern Front in the winter of 1941 alone, Germany lost 180,000 horses. Berlin continued to delude itself that Russian military and industrial power was crumbling, while in reality it was growing. Even when the Afrika Korps was at the gates of Cairo, Hitler denied Rommel the handful of reinforcement divisions that might have taken him to Suez, because he regarded North Africa as an Italian theatre, of marginal importance to Germany.
