I don't know about the USA but in Britain there was a certain level of support for hitler.

Mostly from the Daily Mail. http://greenerblog.blogspot.co.uk/2013/10/hurrah-for-blackshirts-daily-mail.html (I can't speak for the quality of the blog but the picture of the newspaper article is legit) http://imgur.com/xUYxKI9 (from Fire under the carpet by Sylvia Scaffardi- I just really like the way it was phrased,the books a lot more poetic than most academic texts) The editor of the Daily Mail also helped produce the news reels which were played before films at the cinema were also pro-Nazi Party and how a lot of Britons got their news at that time.

Osald Mosely and the British Union of Fascists were also pro-Nazi so they're worth researching. Although if you also look up the march on Cable Street (east London) their views were not necessarily shared by the British public on a whole. But again, the residents on cable street might also not represent the views of the British Public as a whole as it had an incredibly large Jewish population and was particularly socialist compared with other areas.

Also, generally in Britain Anti-Semitism was there but people didn't really admit to it. For example,the 1905 Aliens act was the first act on immigration in Britain and was mostly introduced following the huge number of Jewish immigrants/refugees in the 1880s.

So Anti-semitism in Britain is a confusing topic which I'm currently trying to get my head around for an Essay. It wasn't spoken about but it was definitely there (I've tried and failed to find a quote from a politician at the time about how admitting to Anti-Semitism was a bit uncouth but I've saved my essay on the subject on my work computer and not my home one so I can't find it right now).

In regards to France, I don't know much about it but the only territory not occupied by Germany during the war was Vichy France which willingly handed over their Jewish people to the Nazis. Which could be Anti-Semitism OR could be because reportedly the Germans handed out pretty savage punishments to the French that didn't help them, such as shooting 20 people for 1 persons transgression, so potentially they were just trying to avoid that.
