Who is responsible for violence in Palestine?

There is a verse in the Quran: "Whatever misfortune befalls you is of your own doing." (42:30). This verse gives us a universal law of nature. According to it, you have to do introspection and find out our own fault. According to my experience, all the responsibility lies with the Arabs. They are going against the divine scheme of things. God wants them to engage in the dawah culture, but they have engaged themselves in the fighting culture. So, they are paying the price of this. A verse of the Quran relevant in this regard is: "Believers! If you succour God, He will succour you." (47:7)
