Dave and Rag, I do not even know how much support there was in Germany.
I have never looked into it.
You say there was Dave, but you do not tell us how you know.
And do you know how independent their press was?

I would never suggest that any population is more clever or stupid than any other.

My actual post,
"So IFthe German people supported it, they were duped, deluded or motivated by jingoistic nationalism."

Perhaps it was the latter.
Remarque's book "All Quiet On The Western Front" has the main character and his friends persuaded to enlist by the nationalistic, jingoistic fervour of their schoolmaster.
Remarque was writing of the common experience of Germans, and he would not have included anything unusual or atypical.
