Ok, my last 50 cents in this branch of the discussion tree, I afraid we are going to far off-topic (I propose that we continue our interesting discussion via E-Mail in case of need):
1) Germany's "treatment of the Belgians and French under their control in 1914-1918":
a) Belgium: I guess you refer mainly on the events in Löwen / Leuven / Louvain 1914? I am no specialist on WW I, but I refer to a recent German newspaper article ( http://www.welt.de/geschichte/article131444859/Gab-es-in-Loewen-1914-doch-belgische-Franktireure.html ). According to this there seems to be more evidence for the "Franktireurs" hypothesis.
b) France: I really don't know to what you allude?
I have doubts to draw "causal chains" (Kausalketten) over the centuries. For example, it makes no sense to draw a line backwards from the British atrocities / camps in the Boers riot in South Africa 1900-1902 to the British actions against the American settlers after 1776 or against the riots in Ireland in the 19th century. In contrast, every historical event should in my opinion explained out of his own conditions (time, area, economic / cultural / social conditions, etc.).
