When I was in high school, this book was in my school library. I thought it was so thought provoking that I demanded to buy it from the school. I loaned it out to a friend and never got it back. Years later I bought a second copy, and still I found it to be one the better books of the true inter-working of what the rest of the world was doing while Germany was involve in "The Final Solution" http://www.amazon.com/The-Holocaust-Conspiracy-International-Genocide/dp/0944007244
Sadly, humans can be pushed past the limit of evil if they feel they are being threatened. I studied a little bit of this in Psychology. You should really watch this TED TALK video.
I don't buy into any conspiracies in regard to the Holocaust. It was awful. And as amazing as it may seem to us, it actually happened. We find it hard to comprehend evil so mind blowingly awful these days. Even though we have plenty of horrible things happen in this country on a daily basis, nothing has happened here that even compares to the atrocities of the Holocaust.
The book discusses meetings FDR set up to appear to be concerned about the Jews, yet points out that immigration ethnic quotas were not changed to accommodate them, and the US specifically discouraged the only country willing to take the Jews---Dominican Republic wanted 100,000. It also discussed the supposed neutral Switzerland stamping the passports with J, and Britain that allowed a ship full of refugees to dock in its ports for seven weeks before they turned it away. Do not let the word "conspiracy" detract your interest. For conspiracy simply means two or more getting together. Therefore, by definition any meeting is a conspiracy.
I don't think there was a conspiracy is the traditional understanding of the term, but there were a lot of poor decisions being made. In part I think many were in denial about the situation. It really is so crazy and so evil it is hard to comprehend that it really happened. I think other nations held on to their petty issues like thinking they couldn't handle a whole bunch of immigrants partly because they didn't want to believe these people were going to die if they didn't escape.
