Why is the Koran so hateful of Jews..and mentions Jews dozens of times is a negative way and?

the Torah doen not mention islam at all other than ishmail before the invention of Islam. If Jews are pigs and apes as muslims claim, aren't muslims pigs and apes too since they both come from Abraham ? Why were the authors of the koran so fearfulof Christians and Jews..Why is the sword a commom symbol of Islam.Why are the two groups in Iraq sunnis and shia killing each other every day and why does this not spark a reaction from the worlds Muslim greater than the reaction that was sparked by the cartoons of mohammed.??
