You are absolutely correct that none of this is really known.
And the biggest reason is secret societies (which, in this theory, is the Khazarian Mafia) messing with the history. Even after America was formed, Rots-children and Rock-e-persons went around trying to get Historians to teach history differently. They refused. So, those elite started their own colleges, hired and trained their own historians.

So, we really do not know.

But this theory makes sense of why they have been handling these two wars in strange ways.
