I have a question, let's assume that Germany decide to follow an estern strategy after the Russian-japan war, the kaiser persuaded that Russian is weak and could be destroyed quickly ask to Schieffen to elaborate a plan about a two front war against France and Russia, but with a defensive front in the west and an offensive front in the east in the purpose to knock out of the War Russia quickly.
here three particuliar point, the ww1 is not delayed and happened in the same period and the french spy manage to quickly discover the detail of this plan. (OTL they quickly found about the Schieffen plan)
The french spy will show this information to the french staff that will in their turn show these information to the Russian, now aware of the German plan, they will act accordingly to them.
In the event of a German army succesfull and conquering in the eastern front and aggresive naval strategy, the United Kingdom join the entente side one or two month after the war.
Could the Germans conquer Russia, or would the Russian manage to push them back after the German army were overextended and started to have a lot of supplies problem.
How would the french react, what kind of strategy they would have planned before and during the war ?
How many years the war would last and what would be the consequence ?
