The older generation of arabs didn't hate the jews. They were consumed by arab nationalism which flourished in the 50-60's of the last century.In fact one of the leading Egyptian nationalist was a jew, René Qattawi. Arab governments ever since took advantage of labels like zionism to control its people. While Israel was building its economy , arabs were too busy blaming israel & the west for poverty, weak economy, poor education & corruption. When egypt was having crisis with heroin in the mid 80's it was Israel to blame for  corrupting the youth of Egypt! ever since the conspiracy theories  began. and it kept going on
