Professor Mordechai Kedar (the article is in Hebrew) compares level of terrorism provided from Yaffo, Haifa and East Jerusalem. He arrives to the same conclusions, our paper is reasoning on the basis of Israel and international experience.  Haifa and Yaffo Arabians face everyday reality, translating them message: “there is close to zero chance to push Jews out”. East Jerusalem Arabians face another reality and read another “message”: Jewish power and Jewish presence on the ground  still restricted and hesitant. This reality rises reasonable hope for terrorists to destroy Jews, so it provides much stronger incentives for terrorist violence.
