Stalin was a murderer and a gangster with a long rap sheet prior to getting into the Communist Party. He provided Lenin with cash for operations and Lenin looked the other way. ( Lenin also got tens of millions of dollars from the German intelligence and was sent into Russia by them to destabilize the Czars. He continued to get gold and money for many years.) The admission of Stalin was Lenin's greatest mistake and he was never able to fix it.

Stalin's signing of the Ribbentrop pact was the key event that started WWII.

Quote
In addition to stipulations of non-aggression, the treaty included a secret protocol dividing Romania, Poland, Lithuania, Latvia, Estonia and Finland into German and Soviet spheres of influence, anticipating potential "territorial and political rearrangements" of these countries. Thereafter, Germany and the Soviet Union invaded, on September 1 and 17 respectively, their respective sides of Poland, dividing the country between them. Part of eastern Finland was annexed by the Soviet Union after the Winter War. This was followed by Soviet annexations of Estonia, Latvia, Lithuania, Bessarabia, Northern Bukovina and the Hertza region.


Stalin was an aggressor in WWII as much as Hitler was.
