- Soviets can't send vital/nessecary troops west. Moscow and Leningrad both fall at the end of 1942.
Yes.
And if only because it keeps the USA our of the war.
Japan would not wage war against the USSR and the USA (and China, the UK and France) at once.
So Germany does not declare war on the USA and Roosevelt will not manage to simply enter the war just because ...
This alone would likely mean Germany defeats the USSR eventually.You mean advance in the east?
Yes, it would have cut off the port where 50% of Lend-Lease came in. The least dangerous route too.
Why would Operation Downfall happen? Manhattan project still existsThe Japanese take everything south of the Amur, but are bogged down. If this in in addition to Pearl Harbor, the Philippines and DEI hold out for an extra month or two. The Battle of the Coral Sea is the massive naval disaster for Japan, not Midway. The Japanese might not even take Java or Sumatra. The Chinese do better since a couple divisions are moved to Russia. The Germans most likely take Moscow, but it is retaken during the Winter Offensive. The Battle of Stalingrad might last longer, and the Germans might reach the Caspian Sea. The Iran Supply Route would keep Soviet troops in Transcaucasia stocked up, preventing the Nazis from crossing the Caucasus Mountains. The Soviets still drive them back. The Battle of Kursk would drag out a little longer. The Soviet Progress in Europe would be a year behind OTL.
With more troops to spare, the Allies land in France a couple months earlier as well. There is a Balkan Campaign along with the Italian Campaig, with Yugoslavia cleared of enemy resistance in mid 1944. The Allies move into a collapsing Germany, with the Germans surrendering en masse to the WAllies, but fighting tooth and nail against the Red Army. The WAllies and Soviets link up Along the Bug River.
After the War in Europe ends, the WAllies have executed Operation Downfall, with the Soviets storming Amuria, Manchuria, and Korea. Japan gives up once Tokyo falls
tl;dr: Japan does worse and the Germans do better.
Would the Soviet commander that won Stalingrad be sent east or to another location? Would Germany make the same mistakes as done otl in Stalingrad? The loss of the 6th army makes a significant difference.
And if Japan invades, those formations are heading to Vladivostok, not Moscow. In addition, the Persian Corridor was not operational until mid-1942.It would not do mouch, at least not once the route over Persia worked for Land-Lease to Russia. Spain lacked the tanks and anti-tank weapons to oppose what the Russiand had in 1939, let alone later models. Russia also never pulled troops from the Far East to save Moscow, just western Siberia/ Central Asia and once the Germans are defeated like OTL, these forces turn east and crush what is left of the Japanese Army if the Russian Far East Army did not manage to do so by then on it's own.
Could be that America then focusses on Alaska more, come torugh the North over the Kuril Islands and the Hokkaido?And if Japan invades, those formations are heading to Vladivostok, not Moscow.
How does that help anyone?Could be that AMerica then focusses on Alaska mroe, come toruhg the North over the Kuril Islands and the Hokkaido?
It secured the northern convoy route to keep supplying Russia for the Americans again thanks to US airdominance by quality and numbers, whiel also putting main Japanese islands in bomber range quit fatser then the southern route.How does that help anyone?
