Given the fact that Bangladeshis grow up in total-immersion-in-Israel-hatred you're not totally to be blamed for this attitude - only for not stretching beyond your teachers to correct it, and through your knowledge, help change your society for the better.
That's the argument propagated by the Saudis. Of course, the Mandate of Palestine encouraging "close settlement" of Palestine by Jews was a product of WWI, not WWII. Tens of thousands of Jews immigrated to Palestine before WWI, and hundreds of thousands in the next two decades. Why should the Jews of Palestine suddenly up and leave for some part of Germany they had no interest in?
Arab leaders first proposed using terrorism to drive out the Jews to their Turkish masters in 1899. The Turks said no, but once the Turks were gone these leaders started their campaign - probably with British encouragement: "divide the populace so you can rule them" being the dominant colonial mind-set. Apparently you are unaware of the Arab uprisings of the 1920s and 1930s - falsely portrayed in Arab literature as Arabs being the victims of attacks by Jews, rather than (as newspapers and diplomatic accounts recorded) premeditated violence carried out by Arabs with Jews targeted for murder.
I don't think that describes me. One has to be able to apply the same critical standards to yourself as you do to others. I can; it's just that the Jews come out way better than others in such exercises.
Arabs resist doing this because they have been brought up in an honor/shame society. (Of course, it can't be an honorable thing for them to fight a phony and immoral cause, but admitting that is itself seen as shameful.) They need all the help to change themselves they can get; coddling murderous intent or murderous dictators doesn't help.
