“On the 1871 issue I don´t recall the french having to pay for several generations, so it might not have been a nice thing to do, but it was bearable for France, while Germany after WW1 had to pay for a much longer timespan and couldn´t even come up to the monthly expectations in the first time”:
You are right, in fact the French paid even faster than Bismarck intended. But it wasn’t his plan. The plan was to put France in misery. However, 1871 was one nation against another nation, so the war damages were less important. 1870-1871 war was wanted by both Germany (Bismarck) and France (Napoleon III) for deferent reason: Bismarck wanted to nited Germany under Prussia, and Napoleon wanted to reinforce his weakening II Empire.

Well, the German didn’t pay for generation (one generation is 30 years), but the legacy of WW1 stays more (until nowadays, to be true). And as said in previous intervention, the Treaty was renegotiated. Was is funny, somewhere is that the Allies gave to Hitler what they refused to the Weimar…

And Germany declared war against France, whatever the reasons. And invaded a neutral country…
