Do you believe that most people believed that they were fighting a just war? Not an historian's opinion.

Yes I do.
I do not have a vast ego to compare with yours Dave.
I do not believe that I was born knowing everything.
I have not spent years doing research on original sources and I am not over a hundred years old, so I form my opinions on historical periods by reading history books.

I actually find it hilarious that people like you come on here and set themselves up as knowing more about history than the historians.
You even ridicule people for learning their history from history books instead of just imagining how things might have been and demanding that you empty head whims be given equal authority!
