Actually, what I had in mind was a question about whether it was wiser for Japan to go for resources in Siberia instead of the SRA. What is it in the SRA that makes it more attractive than Siberia?
Siberia has the same resources, possibly more of them, some established industry, shorter routes of communication and you dont have to get the US and ABDA involved in the whole mess.
The Russians, on the other hand, are fairly well screwed. Not only are they facing life and death at the gates of Moscow but they cant afford to divide supply and forces between two points. In addition, its a 2-week rail ride from the Urals to Vladivostok. To top that off, despite what Mogami said, the Trans-Siberian runs perilously close to the Chinese border, south of Lake Baikal. The Russians would not have much ground to give; 100 miles tops, a lot less in many places. You'd only need to hold the rail line in a few places to give the Russians bad dreams.
Also, the interesting stuff is not in Siberia per se, its on the Pacific coast. It is possible to make an amphibious landing and take the entire seaboard. It was not any more ferociously defended than Malaya.
So the theory is, instead of hitting the PI and the SRA, drop all that stuff on Vladivostok. Simultaneously, make a thrust through Mongolia and cut the Trans-Siberian, this will render the Russian Far-Eastern forces useless in a few months of even piddling combat. That done, sue for peace. Neither England or America would be involved. America would eventually get in it, but their beef is with Germany. By the time anyone gets around to moving you out of Siberia, you have organized some semblance of defense. Youre gonna lose anyway, but if youre Japan that happens no matter what you do. It will only be you vs. USSR, its questionable that the US and UK would want to get involved in a war that they have nothing to gain from.
And mdiehl.....Siberia is probably the next most awful tank terrain in the world after jungle. Its all forest and there are no roads to even speak of.
So just a bit of armchair generalship. No serrious historian would be doing this but I can. Incidentally, does anyone know if I can actually try this in WitP? Does the US enter the war even if I dont attack them or the Brits?
A LOT of errors in this post. First, the Russians (thanks to Sorge) knew in advance what
the Japanese were planning and where they were going. The Siberians were only sent
West AFTER the Japanese committed themselves to going South. And if you are talking
about cutting the Railroad, you are talking about some of the better Tank Terrain in the
world---the great Mongolian steppe. Nomonhan proved that Japanese overland logistics
were lousy, as it took them months to advance over the terrain Zhukov took back in
days.
Also, Siberian Resources were primarily more of the same things the Japanese were
getting from Manchuria and Korea, and not what they needed (especially oil). And the
Russians were not "on the ropes" by a long shot in their fight with Germany. Hurt, yes,
but even in 1941 they were still out-producing the Germans in Tanks and Aircraft. And
"Marshal Winter" would be every bit as much on their side in North Asia as in front of
Moscow. The forces the USSR had in Siberia in early 1941 were stronger than the ones
that had kicked the Jap's teeth in twice already. With their spy system in place, they
were more than capable of doing it again. Not to mention that failing to move South
in 1941 would mean that the "Two Ocean Navy Bill" would have put the Japanese forever in the second rank before they could move to gain the resources they really needed---
and continued reinforcement of the Philippines and Malaya would make it more difficult
to try for the SRA with every passing month.
A Japanese attack on the USSR is a bit of a break for Nazi Germany..., and a total waste
of effort for Japan. She already had a "land war in Asia" sapping her strength in China.
Another one in Siberia/Mongolia to try and sieze resources she already had in reasonable
amounts is a step backwards. And to answer your final question, the US WAS going to
come into the war as soon as Roosevelt could muster the political support. If you check
the overall "polling" of American attitudes during the period 1939 to 1941 you will see
that he was getting there even without Pearl Harbor. Maybe not against Japan initially,
but once war was declared even just on Germany American production was going to make any hopes of Japanese expansion into the SRA a "pipedream" in short order.
