Thats debatable. His colonial sales and actions in and after WW2 greatly changed Western Europe and its power structure. While as SU he launched a grand invasion of Europe and slaughtered millions, the political situation he created as a result was not one that is much different than before his invasion. The EL was reintroduced as a result, yes, but many old rivalries still remain which is why theres an Entente.
He made no colonial "sales:" those lands were forcibly taken from him by Liberia and her allies. The only seminotable thing he did as France was drive it into the ground by continually joining the wrong side in the wars. Perhaps one could point out how France led the way in the anti-communist activism (combined with Iberia and Russia, I might add), but the USSR changed the political dynamic hugely with their invasion. Italy is no longer queen of the mediterranean; the EL was re-formed; Germany was torn to pieces; the USA was capable thereafter of establishing an Empire of the Western Hemisphere (though their own invasion of South America is just as much to blame for that; I mean the extension of the US' sphere of influence into northern Europe). Like it has been said before: nothing like a war to shake things up. The very
notion that this war did nothing is silly. I might point to Africa and East Asia, which both experienced changes diplomatically and economically. Because of Italy's sale of land to Abyssinia (in turn caused by the USSR's invasion), Abyssinia was able to sell itself as one of the major spokesnations of the continent. The cession of the CSA also lent to the creation of a mostly-independent Africa.
And if I want to get more specific, allow me to point out the following: 1. The USSR's invasion delayed Germany's nuclear weapons development. Had the USSR not invaded, Germany would have built the bomb first, drastically changing the international outlook as nuclear power would
not have been used for war first.
2. The USSR's invasion changed the political climate in Scandinavia: Norwegians lost faith in the Union and rebelled, creating in the long run the present-day nation of Norway.
3. The USSR's invasion changed the political climate in Central Europe, creating the Entente out of the ashes of former German hegemony, and also helped give the German Civil War more heat. Now the Germans are rather aggressive; hmm, what could that possibly mean for the world?
4. The USSR's invasion destroyed the former credibility of Communists across the world. Never has their reputation been so horrible: the Moscow Pact (now Socialist Security Pact) was much more respectable than the SSP (I see how this can be debatable; just let me say that where, formerly, communist parties had existed in most nations, now they are practically gone from the West).
5. The USSR's invasion spurred on the East-West rivalry between Nippon and the USA. Although this fizzled out (disappointingly), it began a cold period which changed the political situation in Nippon to support the Nipponese Nationalists.
6. Extended from above, the USA elected an isolationist as president, which destroyed the ATO and caused embitterment which was not helped by the fact that the USA was forced to use the nuke in war. Had the war never happened, the ATO might still exist, or at least there wouldn't be so much enmity between Europe and the US.
I could go on, but you get my point. I haven't even touched on the Balkans, the Middle-east, or West Africa.
