No link, no name of the plan... Sure, why would anyone want to check?
By August, 1945 Stalin had only 43 transports in the Pacific (tank carriers and troop carriers) and almost all of them - from Lend Lease. How could he "finalize" anything, when he simply didn't have the carriers to deliver army to the war theatre? And how do you expect him to organize a "thrust onto the very mainland of Japan" with no transports and no land border?
For comparison - D'day had almost a hundred times more transports (~4300) participating in initial invasion, that's not to mention 11.5K support aircraft, 1200 combat ships, etc.
This is beyond stupidity.
