As far as I know the main defense plan of the CSR was to hold the Germans and wait for the Allies to open a western front.
On the other hand it seems to me that the French plan was to just hold the Maginot line and not to enter Germany. No idea if the British had any plans at all.
So I would like to ask, what would the CSR government have done differently if they hand been aware that there would be no help from the Allies from the get-go, but are nevertheless still sharing the border with great bogeyman, Germany.
Also when would they become aware of this little tidbit, are the 20s too late or too early?
