And yet you just introduced them into evidence as if they were true ...
And, so far as I know, they are true.
They are quoted from an author I consider learned and reliable.
In response, our FRiend Olog-hai posted a link which disputes them.
So I acknowledge they are disputed, while at the same time I doubt the veracity of those doing the disputing.
As I said above, the Rosen book, Saving the Jews is an enthusiastic full-throated defense of Roosevelt's actions during the 30s and 40s.
Sure, an impartial jury might wish to look at both sides of the case, but I would not automatically dismiss as "wrong" every point of Rosen's which is somehow disputed.
