This will never work. First, the French and Russians would wait until Russia completed its mobilization. The hammer is likely to fall on the Austrians and the Germans would be stuck trying to attack two fully mobilized enemies
All French attacks OTL are defeated by superior numbers which wouldn't be the case in your scenario
Where are you getting this ? In every WW1 thread you have a completely different perception of reality than most other users.
I don't understand your scenario. So Russia and France wait until Russia is fully mobilized.
Germany deploys 2-3 armies (lets assume 2 so that the West is strongly defended) to the East and the rest to the Western Front with a reserve for a possible French offensive into Belgium.
Germany starts fielding another Army and Russia and France attack when both are fully mobilized.
The attack into Eastern Prussia would be a disaster with 2 defending German armies. Either one or even both Russian armies are destroyed. This would alleviate pressure from A-H because Russia would be forced to shift at least one army to the German front.
So there is no way that A-H breaks and Germany has enough troops to better press their advantage during the Munition crisis later on.
And I don't understand how France is supposed to threaten Germany. If they avoid an attack through Belgium they are limited to the narrow border region. Given their performance IOTL I don't see how they would break through here.
If they attack Belgium we are probably going to see some nasty diplomatical consequences and I still doubt that the French Army could break the German reserve armies who would rush to Belgiums aid.
How is removing Britain from the occasion and assuming a more defensive stance the recipt for a German disaster.
France is basically free to execute their offensive plans which is bound to be a disaster and Russia isn't going to perform better than IOTL but with stronger opposition.
Without an earlier and wide reaching POD France and Russia need to roll a series of sixes to avoid a disaster in 1914. Crushing Germany is deep in ASB territory from my PoV.
Given the population and the military expenditures Germany has more available potential. Even if Russia and France significantly raise military investments Germany has simply more breathing room left to intensify the arms race.
The scenario here discussed is no German wank. A German wank would be "no naval arms race", " Germany raises conscription and military spending to french levels"
and a more balanced strategy with enough troops in the East.
