"That is shown from diaries, letters and recollections."

If, and only if, you call all who didn't agree liars, which is, without doubt what you do.

You do the same with Israel, putting only the one side and calling the other side liars and murderers when many more Palestinians have been, and still are being, killed by IDF than vice versa.

Your idea of balance is "My side is right, so I won't look at contrary evidence".

Funny that!
