I don't believe in racism. Arabs were in fact violent before Islam and Islam is itself also violent. But wether we like it or nor not, we must admit that both Arab anti-Semitism and Islamic terrorism has its roots on Western Jew hatred.
Arab/Muslims were always violent but did they not target specially Jews, they did persecute Jews since the beginning of Islam just as they would persecute anyone who was not a Muslim. Sometimes they targeted Jews, other times they targeted other peoples. It was just a strategy of any evil empire, destroying others and conquering land.
But Islam was quite dormant during the last centuries, they just kept it as a tradition or a religion without paying too much atention to the violent Koran and Hadiths.
At the beginning of modern Zionist movement, some Arabs were willing to accept a Jewish State, it was the Jordanian king who wanted Israel to be 47,000 sq km large, including half of current Jordan. It was only when Western anti-Semitism and anti-Zionism was known among Arabs that they began to steadily target Jews.
Arabs are undeveloped as, any other countries, tend to blame others for their own problem and find spacegoats. Anti-Semites lies about Jews controlling the world wealth and politics fit very well among Arabs who were already looking for someone to target. But while anti-Semites in the West would only attack Jews (they couldn't attack theselves), Arabs used the whole "Jewish controlled West world" as a spacegoat to keep the power of their dictatorships. They attempted to do it by socialism and communism at first (Most Arab leader were secular pro-commnunists, Nasser, Hussein, the Syrian Baath pàrty, Lybian Kaddaffi). But when they failed, they tried to relive the dormant Islam.
