I never said it would be a quick victory, but we're seeing a Soviet military whose officer corps is gutted , with no lend lease, and a possible alliance with the Japanese in the East. You have the British perfectly poised to hit Baku if not take it from the south, a naval force able to bombard the Soviets from the Baltic and Black Seas, and a population willing to revolts which the Allies will embrace rather than turn by brutal racist ideology. The Soviets may survive East of the Urals, but they aren't winning. Without aid the mobility lend lease gave them is gone, not to mention the lack of oil once again due to the vulnerability of Baku. I also see Poland joining in on this which makes the threat to Ukraine, and Soviet food, a reality. It won't be in a year, but it will be brutal for the Soviets past that. Having to rebuild their officer corps with limited mobility and no air cover...yeah, good luck.
