@Dalwin:
Why fight if you don't have to?
Why 'hit' Germany (still in remembrance as a pretty nasty foe from WWI) in the East, if you can get the Baltic and Eastern Europe without a shot fired?
Germany, when at war with the Allies, will, if rational, not go to war over the SU scavenging in Eastern Europe.
There also does not need to be a 'gobbling up'.
They are friendly communist republics (after a while).
@Axe99:
WWI relates to WW2 as far as the old adage of the cheese eating surrender monkeys and there supposed inability to learn goes.
In WWI the French army had pretty much bled itself against the Germans from day one.
Often with little to no gain and pretty much the same went for the Brits (who smoked their 'professional army' up until mid 1915 and then managed to waste to other armies til the armistice).
The French did that because they had a alliance with Russia and that required them to put pressure on Germany (read: attack).
They were however woefully unequipped for that task.
The result was the 1917 mutinies (which was the French poilus vote of non-confidence in their general staff) and a change doctrine, but in the end England and France were still unable to beat Germany without the assistance of the USA (which is another important factor since WWI demonstrated that the two big old powers, France and England were no longer capable of containing the upstart Germany on their own, even with their colonies).
The French drew the correct lessons from WWI, but they failed to evolve.
The Maginot line was well and good... before the advent of serious airpower, paratroopers and hollow charges, but even then it would have served its purpose.
The command system was adequat... before the advent of the radio, but nothing substantial kept the General staff from applying modern communications.
Etc.
@Blobbleu:
I would like you to read John Mosiers The Myth of the Great War.
If you look at Wikipedia, my favourite example being the Siege of Liege, there is strange dissonance whenever the germans did win or the Allied 'won' but somehow did not conquer anything worthwhile (Passchendale for example was a town in the middle of nowhere; no strategic value, no railroad connection) and suffered severe losses.
Let me highlight the example of the Siege of Liege:
There is lots of information, troop depositions, etc. and then we start with 'Battle': German Attack 6-7 August
You read of retreat for the Germans, them being repulsed, disorganized, suffering heavy casualties, back and forth, running the gauntlet. Advances are checked, casualties inflicted, everything reeks of the Germans doing a very poor job and being outclassed.
And then suddenly they are in Liege, having knocked out two forts (no mean feat) and have suffered only 5000 casualties (which would be, as per the era, between 66% and 75% wounded and about one in 4 dead).
The rest of the siege is swiftly falling forts.
Which leaves a dissoance:
The germans were doing so poorly, how did Liege fall?
And it goes on.
Mosier does a good job of providing an alternate look (based on French sources, which for the most part are bared to the anglophone internetsphere) and explaining the dissonance.
It might even explain why nearly everyone has an 'remembrance day' on 11.11. and silence at 11 o'clock and why Germany does not but Karneval (Germany mardi gras, more or less) is starting on 11.11. at 11 past 11 o'clock.
