What if U.S. invaded Soviet Union?

Thank you.

Based on how the Japanese command and the decisions they would have likely made, there would have been almost no impact on the war. The Iowa class battleships, which were awesome, but arguably had little impact strategically would have had their resources shifted to speed up the building of the Essex class carriers, with little expense on the Soviet Union or the British. The US would not need to defend California or even shift resources for it-the US can easily just activate their militia (remember the Second Amendment). Japan would not have invaded (or even thought of) invading the continental US, and capturing Midway or Hawaii (a formidable task in itself) would still have made it hard, if not impossible, to win in an invasion. Japan would have needed more ships and men than planned for Operation Downfall, which would be impossible, considering only the US could muster that large of a force. Japan would also have to deal with China, the threat of the Soviet Union, and the British. It would have been a waste of a victory, as Japanese troops would probably have been slaughtered on the beaches of Midway.

Now if the Japanese political and military leadership was headed by people who know what they’re doing, then absolutely! This would have set the US back quite a lot. The Japanese then should have adopted a strong dug in defence, operating the capital ships only in range of powerful land based aircraft and submarines, coming up with an effective convoy system, and working with the army to coordinate operations. This could have taken up so many US resources to beat that the Soviets would have had a lesser victory at Stalingrad, and Rommel could have held out longer in Tunisia if there were less forces in Operation Torch.

The best thing for the Japanese to do, of course, is to attack the Soviet Union. The Far Eastern troops were grossly exaggerated by the Soviets (which the Japanese willingly believed after Kahlkin Gol), and replacements for the ones that have been siphoned off west were generally worse, with little training. The Japanese air force was less outnumbered by the Soviets than the Germans were, and had even more of a quality advantage. The Japanese could have easily destroyed most of the Soviet Pacific fleet in days, destroyed the Red air force in an even more total fashion than the Germans did, and captured Vladivostok. Japan’s decisions are kind of stupid when they basically thought that they had a greater chance of defeating the US, a nation that has had their resources not yet tapped in any way (except Lend Lease) than the Soviet Union, whose cream of forces were destroyed in 1941, their replacements almost always understrength (most Soviet cavalry divisions were less than a third of a real division, rifle and tank brigades were only a quarter of even a small World War 2 division, and rifle divisions were only half as effective as a German infantry division), suffered enormous equipment and officer shortages, and had horrible logistics. In addition, many Soviet units had little training, and were expected to get that on the job fighting, leading to huge casualties. And that’s the west! The Far East forces were infinitely more inferior. As for oil, Japan could have reduced American unhappiness by doing withdrawing partially from French Indochina and reducing operation in China, both of which are necessary anyway for mustering forces. Diplomatic decisions are much easier to reverse than military ones, and the US would have saw the invasion as a removal of a threat to American interests in the Pacific (both Japan and the Soviet Union would have their hands tied up). Coupled with a better German strategy, the war in the East could have been won in 1941.

I strongly recommend you read Nigel Askley’s books, who give the most detailed account of Operation Barbarossa, detailing German and Soviet mobilisations, production values, and reinforcements, all used for a war simulation. I haven’t bought them all and don’t read them entirely (only the parts I’m interested in), but they are very good books, and more are being written. The part about Soviet Far East forces (Volume 3B) is very well done, and they also cover the Soviet and German air forces and navies.

@KurtGodel7:

The Type XXI U-Boat had a rubber coating, making it difficult to detect. Also, its streamlined design allowed it to move faster underwater than it could while surfaced. It had a sophisticated electronics system.

Also, if you’re giving Germany the Type XXI U-boat in 1943, then you should also give it the kinds of torpedoes it had available in 1945.

Hmm maybe the underwater launchable Do-Werfers as well, too?!
German had some successful underwater launchings with, I think 15 or 28cm Do-werfers ,in 1942 near the Penemünde area.

Thank you Tall Paul.

It is early yet Garg.
The Civil War was lost in the West, starting with Nashville and Vicksburg was a greater loss than Nashville.  I agree that a Southern victory at Gettysburg would not have equated to the fall of Washington or an armistice, despite Lee’s hopes for one.

No, The back half of russia is much like Alaska, a frozen wasteland. It would take them forever to get troops north of manchuria, and supplying them would be nearly impossible. There werent any natural resource up there so the japanese had no interest in “capturing” (if you can even call it that) north russia. It would be smarter to send troops into china or inda, where the resources were.

@Audacity:

Very interesting.  Can you direct us to published material about this?

I certainly can. My best source is “THE SS, Hitlers Instrument of Terror” by Gordon Williams. It was actually Himmlers idea to incorporate Muslims into SS units as an experiment. They used their new power to quickly murder “religious infidels” including Jews and were eventually given only police authority because of their lack of obediance to SS order. They had their own special collar tabs but were never issued an SS Honour cuff on the sleeve. Himmler had these units engaged in the Balkans, around Greece and a few other minor battles. They were actually fought VERY poorly and were taken off the front lines. For the rest of the war, the units that weren’t disbanded were used for anit-partisan activities and were “attached” to another SS unit but did not have the title SS.

It was a brief experiment that elated Himmler. Hitler has little to do with it as far as I know.

PS – thanks for all the Karma while I’ve been out sick for the last month. You guys rock.

@marine36:

But you see, Roosevelt wanted war with Germany, to help his buddy Stalin, so it would have happened eventually.

And I do believe the Tommies whipped Rommel all by there lonesome at El Alamean, though it is doubtful such success would have lasted once he got back to Tunisia and was reinforced.

The 6th Army. Yes, it was a significant number of men. A quarter of a million Germans is nothing to sneeze at! Personally, I don’t think moral is a factor in modern warfare, at least it isnt in the Corp, but you may be right there as well. It is reasonable to assume that the German soldiers are different from U.S. Marines, and are still affected by moral.

Rampant behavior of rape and murder? I am certain SS divisions maintained their dicipline in Russia, it was not until after the fighting had ended in an area and the soldiers had moved on than Himmler would move in with his death squads. The men of the SS where fine soldiers, do not label all of them barbarians for the actions of Himmler. Perhaps you have information that proves otherwise? Well, despite Himmler’s ruthless treatment of Russians, many Russians still did side with the Germans.

the SS were bastards, the waffen-SS were just foreigners. Can understand them a bit: who doesn’t hate RUSSIAN communists?
