Yeah the French of 1914 definitely were no pushovers. They were as gung-ho and aggressive as you can be in an industrial society. Consider that after the Prussians beat them in 1871 they were so angry they had to go and conquer half of Africa just to vent steam. The place wasn't worth a damn and the natives were a bother and the heat was terrible, but they were so angry they went and trekked all the way from Dakar to Sudan and conquered every place in between like it was no thing. And even picked a fight with the british in Sudan because they wouldn't let them conquer their way to the red sea and part the waters just by the force of their anger. Those guys were aggro as hell and as jingo as they come.Look at the people who were running France in 1914 and compare them to the people who ran it in 1940. Apathy was simply not Clemenceau's style; this was a man who liked to duel people for fun and insisted on being buried facing Germany just to spite the bastards.
The main reason why the French political and military class were so apathetic in 1940 was because they were the generation who fought in the Great War. They were the generation who grew up believing the nationalistic myths that France was a great nation with a great military only to see that great nation bombed and gassed into submission by German artillery and that great army massacred in the meat-grinders of Verdun, Ypres and the Somme. They had seen millions of their comrades die in a long and bloody war whereas their grandfathers only saw thousands die in a short offensive one. Their entire world had been turned upside down. It takes more than simply losing your capital in a series of wars that you only read about in books to cause that kind of existential crisis on a mass scale. It takes something like the Great War.
Not to mention that even in 1940, enough people still clung on to those myths to make the Free French a thing. Imagine how many millions more would have still done so if the Great War had only lasted a few months?
