What if U.S. invaded Soviet Union?

@martin-of-tours

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.

@wittmann:

Worsham: I noticed it was today in 1920 that Polish troops under General Rydz-Smigly held a victory parade up the main road in Kiev, celebrating their 7th May capture of the city.
Their tenure of Kiev only lasted a few weeks.

After studying this conflict, you can get a better understanding of the Soviet willingness to divide Poland with Germany.

The second Italian Facist regime : la Repubblica Sociale Italiana (RSI) was set up today, with its capital, not in Rome, but Salo, a small town in Lombardy on Lake Garda,  Northern Italy, where the RSI had his Foreign Office.  
Mussolini was its head, but it was nothing more than a German puppet, dependent on its military and financial support.
Mussolini had been rescued from captivity in a daring raid by a soon to be famous German SS Colonel, Otto Skorzeny on September 12th.
Italy had  surrendered on the 8th and the Allies had  landed at Salerno on the 9th and were fighting the Germans in the south of Italy at this time, though they had not yet captured the city port of Naples.

BUMP This is cool if you have not seen it yet.

@Raunchy:

At least 749 U.S. sailors and soldiers would be dead by dawn.
Code-named Exercise Tiger, the ill-fated D-Day dry run was at the time America’s costliest incident of the war (only Pearl Harbor was worse).

:roll:sigh, people just dont know anything about history

But very interesting article, I dont blame you for the  author being an imbecile

@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.

In some of my other posts on this forum, I’ve described how even in 1940 (when the U.S. was still technically at peace with Germany), it had devoted a significant amount of industrial potential toward winning the air war against Germany; with plans to considerably expand the effort over the next several years. America’s strongest single asset was her industrial potential, as Hitler clearly understood. But that potential was going to be increasingly turned against Germany, whether the U.S. was technically at war or not.

Hitler’s plan to counter this was to expand Germany’s industrial output over the short-term, so that he could at least keep pace with the air war over Germany in the long haul. His method of expanding Germany’s output included industrialization and conquest. The industrialization aspect of his plan meant that instead of putting everything he had into weapons output for 1941 or 1942–in a massive effort to crush the Soviet Union–he had to divide his nation’s economic activity between short-term military production and long-term output increases. The result of all that industrial investment was that Germany increased its aircraft output from 16,000 planes per year in 1941 to over 40,000 planes per year by 1944. It also increased its military production in other categories, such as tanks and V2 rockets.

In late 1941, Hitler knew that his window of opportunity to win the war was relatively slim; and that 1942 would be critical. Germany had to win a decisive victory over the Soviet Union in that year, both to take pressure off its eastern front, and to provide it with the raw materials and manpower it needed to hold its own in the air war over the long haul. Hitler believed that the overwhelming majority of America’s naval strength would be needed in the Pacific to counter the Japanese; at least until the end of 1943. That gave him what he believed was a two year window with which he could sink the American Lend-Lease Aid pouring into Great Britain and the Soviet Union. Sinking those ships would increase Germany’s chances of obtaining the victory over the Soviet Union it desperately needed.

However, the Japanese Navy proved less adept than Hitler had hoped. The Battle of Midway occurred six months after Pearl Harbor. That battle took the naval pressure off the U.S. in the Pacific, and allowed it to focus more of its efforts on convoy protection in the Atlantic. More generally, the failure of the Japanese military meant that Japan would be far less successful in taking military pressure off of Germany than Hitler had hoped.

In 1942, the Soviet Union outproduced Germany 3:1 - 4:1 in tanks, artillery, and other land combat categories, and even 2:1 in military aircraft. It also fielded a much larger army than Germany. Thus evaporated Hitler’s hope of a decisive victory on his eastern front.

Had Hitler not declared war against the U.S., large amounts of American Lend-Lease aid would still have flowed to his enemies in Europe. Over the long-term, he still would have needed to devote a significant portion of his military production to defending German skies and German cities against American-made bombers. He would have lost out on the Second Happy Time (see http://en.wikipedia.org/wiki/Second_Happy_Time ), which would have resulted in a stronger Soviet war effort for 1942. On the other hand, he wouldn’t have had to deal with the U.S. invasion of Algeria in 1942, its invasion of Sicily and Italy in 1943, or the Normandy invasion of '44. It’s easy to say in hindsight that the harm of the American invasions exceeded the benefit of sinking that Lend-Lease shipping in '42. But that distinction was less obvious at the time.
