You completely miss the point Jim was making about Gary Sheffield. He wasn't saying that his views about the war were not similar to those you have been expressing, but rather that Sheffield clearly would disagree with your repeated assertion that those views are generally accepted - in fact he specifically says that they are not, and thinks that they should be.

At this time the view that the war was well waged and that the slaughter was justified by the outcome does not appear to be the generally accepted one. The fact that a number of academic historians might hold it is interesting in its way, but hardly conclusive. Though whether a particular historical view is in fashion or out of fashion is not in itself that significant.

It is common in public inquiries into public scandals for the final report to end with formal conclusions which sum up against the evidence. That is a temptation into which academics also fall at times.
