"Mein Kampf" was written in 1924 and Hitler died in 1945, so copyright has not expired in the US and in Europe. We may argue over who owns the copyright, but not over the fact that it still is copyrighted.

That is not a "fact", or at least not a complete fact: most of the countries of the world, with most of the world's population living in them, have a life+50 term of copyright. Even if the work is still under copyright -- setting aside the idiotic issue of determining ownership now -- in Germany and the US, in most of the world, the book no longer has copyright subsisting in it. And that "most of the world" is about to get a lot larger, when the "life+60" copyright in India expires, if it hasn't already. (Not sure whether India has the "and to the end of that year" wrinkle, or not.) Whatever the status of the work in Germany, from where I am typing, Mein Kampf is, for better or for worse, at least in its original language, a public domain book.
