China could have won the Second Sino-Jap without US intervention.

Thank you for taking this argument. As you know, this is my 2nd debate.Germany VS RussiaI will start outside of China. I belive that the Soviet Union would be able to stop the Germans. They might not be able to push all the way back to current borders, but they would still hold the line. The Soviet Union was already enmassing troops from the eastern front behind the front line, getting ready for a counterattack at the time. They would have been able to save Moscow, Stalingrad, and Lenningrad, denying Hitler precious oil and industries. Though without US support they wouldn't have the same momentum, they would be able to hold the Germany Army. The winter time giving them time to construct fortfications similar to those built during the Battle of Kursk.United KingdomWinston Churchill would have never lay down to the Germans. Never. The huge casualties they infliced on the Luftwaffe ensured no further invasion of Great Britain, at least for the time being.Japanesse RecourcesWhile I was still hoping the Oil Embargo was in place, I will continue my argument with this point accepted. Japan even though being able to buy oil from the US, would not have "infinte" oil supply. There is a simple matter of currency. Occupying so many territories, and holding them against enemies was costing the empire a lot. Sooner of later, the government would soon run out currency to buy the precious oil they need to continue pushing into China. I am assuming since the US never put the Oil Embargo on Japan, they have had no need to invade the Philipenes and capture those oil supplies, which would basically give Japan free oil... well not free, you know what I mean. Also we are still assuming that China can buy supplies from other countries including the USSR and the US.Battle PlansI am also going to assume that Chiang Kai Shek still wanted foreign support. But, this hope is much dimmer due to no US oil embargo. Chiang would still dedicate his forces to defend Shanghai, forcing the Japanesse south, then eastward from there into Nanjing. Since there isn't as much hope of Foreign intervention, Chiang wouldn't have dedicated all of his German trained Divisions into the Battle of Shanghai.We know for a fact, China was able to hold out against Japan, before the US intervened, China had already won quite a few battles, and have effectivley reached a stalemate in 1939. Both sides at this point would have access to mobililty, such as tanks and trucks.After this, we see China holding back after the Winter Offesnive. The Winter Offensive, though considered a defeat proved that China was now able to launch offensives at Japan. They simply chose to hold in, as by this point US had commited to help China more. Without US help, China still have the strength to hold the line, and most importantly, take back territory gradually.This is supported by the fact, that the supply lines stretching from Shangahi to Wuhan, is strenous to say the least. Guerilla Warfare behind the front line conduceted by the Eighth Route Army, would ensure limited supply for the Japanesse. The Nationalist Centaral Army, would be able to take back territory, slowly.
