Why is the mein kampf and other anti jewish books popular in the islamic countries?

After WWII ended, the UN voted to send the Jewish survivors of the holocaust back to Palestine, ignoring the fact that Palestine was already populated with modern Palestinian Arabs. The residents already there lost their homes, jobs, everything, in the process, and war ensued. The Palestinians were sequestered into ghettos and have been treated by the Jews like the Jews were treated in the European ghettos during the holocaust. The holocaust victims and their children became the predators. The rest of the Arab world is pissed off about it - imagine that. The whole situation was handled very, very badly from the beginning, with the US pretending the holocaust wasn't happening, refusing entry of European Jewish refugees, etc., etc., etc. Add to that, the millenia-old family feud between Ishmael and Isaac because their mothers were married to the same man and couldn't get along... This is family dysfunction at its absolute worst.
