I think the term "Greatest Generation" applied to WWII vets, because WWII was really a World War whereas WWI was mostly in Europe. Although it did spread throughout Europe, so did WWII and beyond to the Pacific and Asia. Japan, Germany and Italy had invaded country after country and they were all pushed back and forced to surrender. So much for Imperialism, Nazism and Fascism..............I think what the sons of WWI vets achieved in WWII, made the fathers feel proud, as much as I became the first born of the same generation. Question, do you think the same could be accomplished today? With all the techno, yes, without it, no....IMO.
