The French character isn't as developed as the German from what I remember.
The only other book in which Verne was similarly pessimistic that I'm aware of is 'Paris in the Twentieth Century', which was originally considered too negative for publication.
from a novel written in 1879!
Also interesting, that the main protagonists originate from an inherited fortune of a lost hindu prince
I'm convinced by reading "Britain's War Machine" by David Edgerton that Britain's darkest hour was not Dunkirk but Japan's entry into the war and its lightning capture of most of SE Asia.
I was making the point that the British gov also used the resources of a Hindu country.
