All based on counter-factual speculation about an event that didn't happen. There are literally Zionist propagandists who claim a second Holocaust was coming but then Stalin died. Wow. First off they present no proof and secondly it dove-tails nicely with the mainstream idea that Stalin was bad, bad evil man while a revisionist douchebag like Khrushchev was actually a good boy trying to turn things around.
Again, you're absolving them of guilt without even reviewing the evidence in the case. Likewise, it was Beria and not Khrushchev who for better or worse put an end to the Doctors Plot incident rather than Khrushchev.
The campaign against cosmopolitanism was not an anti-Jewish campaign but more of a campaign against what we today call imperialist "globalization":

We're getting a bit off-topic aren't we? First you tell us that anti-semitism is a special type of racism that is different from all other types of racism then you try to prove the validity of the threat against Jews using…the example of other groups who allegedly received discriminatory treatment! Well, that is a leap, being anti-black doesn't make one an anti-semite and in fact the Jim Crow South and colonial British Africa were surprisingly tolerant of Jews!
I think you should ask what Stalin hoped to gain from carrying out a pogram against the Jews in the USSR. This was a man who tried to build a nation for Jews within the USSR and after the Holocaust the idea of a second Jewish homeland in Crimea was contemplated but never carried out due to the obvious unfairness of it.
Its not a secret that many of the Soviet Union's most enthusiastic supporters in the West were Jewish. It doesn't make much sense for the Soviets to want to waste the credibility they gained from destroying Nazi Germany by persecuting Jews.
Likewise, to my knowledge, the deportations occurred during WWII and these minorities were allowed to return to their homelands afterwards, though some preferred Central Asia. There is evidence that they did collaborate with the Nazis but whether this treatment was fair is something you should decide for yourself, I would check out the Furr book I posted on this.
This actually isn't so there is damn good evidence that Nazi Germany, Poland, and Japan had intelligence sources and traitorous contacts within the Soviet government and wider society in the 30s. Even Churchill, the French embassy and Joseph E. Davies had fairly decent ideas about what was going on even if their positions weren't the mainstream Cold War orthodox positions of today.
Mossad also operated in Hungary prior to the Hungarian uprising and I don't know how Mossad got a copy of the secret speech but that they managed to obtain it and pass it onto Langley is a fact. Its possible it was passed to them by the KGB themselves but they did have contacts behind the Iron Curtain–the Holocaust had created understandable sympathy for Israel among some Soviet Jews.
