The German attack on Russia started so well, that they started planning their next moves

The German attack on Russia, launched on 22 June 1941, was succeeding so well in the initial phase, that planning commenced for the nexts moves following the collapse of Russia. The Russian campaign was planned to be over by the fall of 1941. At that point, the Germans would be free to concentrate pressure on the British position in the Middle East. With a successful result in Russia, Germany would be in a better position to apply pressure on Turkey. They would press Spain to remove the British from Gibraltar. They would be able to attack Egypt from Libya, through Bulgaria and Turkey, and possibly, through Iran. This is based on the account in Vol.II of the Official History.
