What if France rejected Appeasement and attacked Germany anyway in 1938 as Pre-Emptive strike?
I know France in 1938, was deeply divided to make a coherent foreign policy and dealing with economic problems but imagine for since 1933 they actually doubled their defense spending and thus in this one instance the entire French Republic agreed that Germany was up to no good thus encouraged Czechoslovakia to fight against Germany and prepared for war mobilization regardless of what Britain said. How would this changed the trajectory of the War? Would Britain quickly follow suit and how the Soviets would react as they are tepidly allied with Czechslovakia even though Poland is not allowing Soviet troops to pass
