Left Wing Historical Revisionism

The point being Hottentot is that in those first two cases there isn't really an accepted answer, much less an "ACCEPTED" answer .....unless lots of parameters are set out beforehand.
On the third part really the only possible answer is another question as its a cause and effect string and each step back you take to get an answer opens up another whole new bundle of old strings.

I have heard a similar one being made about the whole beginning of WW 2: when did it become a World War and to what point it was just an European conflict?

Yeah I was helping one of my kids with some homework on WWI, her teacher had said it started on August 4th 1914.(see thats the old imperial hegemony at work) . I wonder if the OP thinks it started on April 6th 1917?
