In general I agree with this article. However, this comment is just factually inaccurate.
It is generally agreed that the decision to kill all the Jews, as opposed to excluding, marginalizing and/or expelling them, was made at the Wannsee Conference on January 20, 1942.
At that particular point in time most of the world was already at war with Germany. It's difficult to see what more "the world" could have done from that point on to keep that six million from being killed.
Seems strange no one ever brings up the USS Liberty at this point, and asks stupid questions.
