Query: I found it quite unbelievable

Although I found quite a bit interesting the overall concept I found to being quite unbelievable. That Stalin intended that the North Koreans would lose the war, so that he intended to drag in the Chinese and that the US would for their own reasons allow the South Koreans to lose a limited defeat so that they could save them after a long fight once they got the US congress to support the war.Its just too far fetched. A simpler explanation would be that Kim a Korean nationalist decided to unify Korea, and Stalin, Mao and Kim all miscalculated the US response. So losing control.
