On what planet is a French invasion NOT a French invasion?
On what planet does a reconnaissance in force (this is how the operation is called in the french orders), involving a handful of battalions, killing 10 soldiers on each side, and stopping once the said battalions have advanced a few kilometers, while the rest of the army sits still on the border, qualify as an "invasion"?
The whole army was sitting on the border, had been doing so for a couple of weeks, and there were no plans to invade Germany.

These guys were NOT cowering in fear of Prussia. They were insulted and they were HAPPY to declare war, and fully expected that France would win again, as always.
Napoleon tried to avoid war with Prussia throughout the 1860s, and even tried to back from a declaration in July, once the actual story behind the Ems dispatch was understood. On the Republican side, Thiers declared, on the 15th of July, to the military leaders "you are not ready" (to which Le Bœuf replied "il ne manque pas un bouton de guêtre). And there had been voices in the military hierarchy that had warned against the strength of Prussia, before and even more after Sadowa. Public opinion wanted war, this is certain, but the idea that it would be an easy one wasn't there (this wasn't 1914).

And the idea that France planned a "defensive campaign" is laughable. The French military was fully versed in the Napoleonic belief in the offensive, and it was embedded in their military ethos all the way through the First World War when it finally bled out in the trenches.
Laugh if you will, but French doctrine, in 1870, in 1914 and again in 1940, always called for defending on the border. I believe the lessons the military leaders thought they had learnt were those of 1792 (Valmy and the like), and the campaign of France in 1814, where Napoleon had fared relatively well (given the odds). I think it is also ingrained in the idea that the French Army was a conscription army, defending "la patrie en danger".
This doesn't preclude, élan, offensive tactics, or use of massed infantry. It just means the French generals wanted to fight on their turf, over internal lines, etc.
