It showed him what? You bring Hitler and Mussolini into the discussion about how the west pooled their resources to destroy these dictators, which, fair enough, is what happened, only after war had been brought to their doorstep by said dictators and they had gotten a pretty bad beating. But this set of circumstances doesn't apply to Stalin, the west never entered into an actual war with him, and the airlift didn't put him under any pressure whatsoever. Hitler shot himself because the red army was half a kilometer from his bunker and Mussolini was dangling from the gallows thanks to italian partisans, and here it's undeniable that this happened due to the western powers allied with the soviets. But they never stood up to Stalin the way they did to the fascists, so how exactly did the west "show him"?
And yes, Stalin's USSR isn't on the map any longer, but it didn't collapse with his death, it collapsed nearly 4 decades later, with multiple leaders in between. But that's the course for most, if not all Empires. Victoria's British Empire doesn't exist any longer, although it too survived for decades after her death. The Spanish Empire didn't die with Charles V, and the Roman Empire was expanding in size and strength after Augustus as well, but none of those empires exist any longer, that's the natural course of history.
