What if Yugoslavia's Marshall Tito has Josef Stalin assassinated in 1946?

It's pretty well known that Tito and Stalin had a major rift following the second world war, with Tito going his own way, and an infuriated Stalin trying to assassinate him at every turn. In fact, something a little less well known, is that Tito was getting a bit bored rounding up Stalin's Russian assassins and having them shot -- a waste of manpower, you know. So, Tito actually sent Stalin a letter in private, found in Stalin's private papers after his death, in which he quite explicitly indicated that unless these attempts stopped immediately, he would finish the problem himself by sending a man to Moscow. And, the assassination attempts promptly stopped. So, it seems perfectly conceivable that Tito could conceivably have indeed assassinated Stalin, if he needed to, to protect himself. So, Stalin is dead seven years earlier than OTL. Now, some of the most significant events in Stalin's career occurred in these last seven years of Stalin's existence. Most notably, - The iron curtain over Eastern Europe -- enforced communism. - The Cold War between East and West. - The Berlin blockade and the Berlin airlift. - The first Red A-bomb. - The communist takeover of China. - The Korean War. Would any of these events be significantly affected by Stalin's death, or would they have proceeded pretty much as OTL, if Stalin is no longer present and his most likely successors take over the role? Any thoughts? My own suspicion, is that nothing actually changes a great deal, with, or without Stalin in these particular years.
