Hitler used the same tactic when it came to attacking France and the Soviet Union. The tactic was to launch well organized, surprise attacks, with lot of its military personnel involved, so that he take them down quickly and effectively. With France, it was an attack through the neutral territories of Benelux, attacking them surprising when the French lacked defenses. With the Soviets, it was slightly different, but yet very similar. Hitler and Stalin had an agreement to not attack each other, and to respect the spheres of interest between each other. Hitler used the fact that Stalin trusted him, so once the German army came close to the border of the Soviets, Hitler attacked the Soviets who didn't expected attack from them. It resulted in quick and efficient taking over of the southern part of the Soviet territory in Europe, just that the end result was not the same as in France, as the Soviets after lot of struggles managed to defeat the Germans, helped greatly by the severe weather conditions.
