>Besides, as an Israeli, imagine a world in which the manufacturers of Zyklon B refused to sell Hitler their product for the purposes of gassing human beings. It might not have prevented the Holocaust, but at least maybe impeded it a little.

Honestly, if the Holocaust was today, we would probably get 10% of comments here trying to defend "both sides". Some people have a need to try to defend every side, even if one of the sides it's asking for them to be murdered.
