The Japanese wouldn't have won if they invaded Russia in 1941.

As Iv said I fully understand that fuel would have been a major problem for the Japanese in this scenario. However I still feel that you are missing the major point of this. In this scenario Germany is still going to be the major aggressor against Russia and would still be the one to do most of the conquest. Japans main goal would have been to simply present a threat from the east forcing the Soviets to tie up much needed assets that they absolutely needed to defend the west. Without these assets the Russians would have lost the western front to Germany. It is absolutely insane to think that the 700,000 man force who had very few aircraft and only a light contingent of tanks would have been able to hold against the 6 million man Japanese army along with however many planes and tanks they wanted to send. Stalin would have HAD to send more troops to the east or the Japs would have swept through all of eastern Russia. Every man Stalin sent to the east would be a man not fighting the Germans on the west which is the more crucial front of the war. Japan only needed to push just far enough to achieve this. They could then seize the eastern Siberian oil fields and while this wouldn't have provided them with to much oil it would have been enough to keep the invasion going. Once Germany was finished beating the tar out of the Soviets then Japan could turn its attention towards the East Indies. So this is not a question of manpower or how well Stalin could defend both fronts at the same time but a question solely decided by whether or not Japan had enough resources, the primary of which was oil, to conduct the invasion at all. And by the way Stalin himself was terrified at the prospect of fighting a two front war because even he knew it would have been the end of the USSR. So now the question of whether or not the Japanese would have had the resources to conduct this invasion. I believe that they would have. During the winter of 1941 Japan had a stockpile of about 50 million barrels of oil. Japan could only produce about 2.7 million barrels a year domestically and an additional 2 or 3 million barrels from already conquered territories ie; Manchukuo and Taiwan. Not a whole lot of oil but still enough to last their country an estimated 2 years. This estimate however was based off of how much oil would be needed to also provide their navy for the Pacific campaign. During the campaign the Japs used an estimated 2,900 barrels of oil every hour. That's a lot of oil. A lot of oil that would NOT be being used in the scenario we are discussing. All of this oil the navy was soaking up could have been used to out fit their vehicles and tanks and planes in the invasion of Russia since the Navy would not have been necessary for such an invasion and could pretty much just sit there and chill in the Japanese waters. So now, yes, the Japs are using a lot of oil to fuel their planes and vehicles but nowhere near as much as what they would have been spending on their navy which means that 2 year estimate could almost certainly be extended. Meaning the Japs had 2+ years worth of oil they could use to invade Russia and then turn to the Dutch East Indies. Just one little extra bit to throw in here. Vladivostok Russia is only 538 miles away from main land Japan. Pearl Harbor however is 4,060 miles away from Japan. So saying that invading Russia was "just outside their reach" is clearly not true and obviously a crap ton more resources would have been needed by the Japanese to attack Pearl Harbor, and conduct several other military operations across the Pacific at the exact same time, then would be needed to push against the Russian border. So basically for your next round ill give you a hand and tell you what you need to do to win. You have to somehow prove to me that the Japanese Ground and Air Forces would have used up more oil to conduct an invasion of Russia then the Japanese Naval Fleets used to conduct war against the US and allies in the Pacific Campaign. This is the only way you can prove that the Japanese would have been incapable of aiding the Germans in the defeat of the Soviet Union. Best regards as always and good luck in your next round. PS. I'm having a great time. Really enjoy this debate.
