Stalin would have starved or simply had them all killed...which history tells us is what he did.
A plan or odea (which would admittedly need to be fleshed out significantly) gives the Palestinians a chance, repeating it with each attack from amongst them, to resolve the problem of Palestinian terror themselves and puts the owness on them to do so (where it belongs)...with a prospect of earning a stable state of their own. If they refuse to do so, and continue to harbor and/or abett terror amongst themselves, then ultimately they are treated as the allies of terror they would reveal themselves to be.
I am rather well versed in Soviet history. Stalin's and Hitler's barbarity are different in degree. True- Stalin's body count was indeed higher even before WWII. But Stalin never came close to wiping out an entire people as Hitler did. Stalin's deportations of entire ethnic groups were extremely cruel but the intent wasn't to murder them so much as to disnfranchise them. It did indeed result in a lot of death among these groups. It was "ethnic cleansing" on a mass scale. But most of those who died did so out of brutal indifference of the state rather than a gas chamber or mass machine gunning. Hitler's Death Camps remain unparralled. Entire families were gassed to death for their enthnicity. They were set up to kill. Stalin's Gulag was not much better but they didn't exist to kill- that was an auxillary benefit- they existed for cheap slave labor.
I hope I never see the day when Palestinians are flushed into the deserts of Jordan, Saudi Arabia, Iraq, or Lebanon to die like flies or subsist on UN handouts.
And from recent studies done- it does appear that Stalin intended a Hitler like holocuast for all Soviet Jews but died before he could see it through.
