This is Zionism: "The chief rabbi of Safed, Rabbi Shmuel Eliyahu, is calling on the government to carry out "state-sanctioned revenge" against Arabs in order to, in his words, restore Israel's deterrence...In the newsletter, which was distributed to synagogues around the country, Eliyahu proposes "hanging the children of the terrorist who carried out the attack in the Mercaz Harav yeshiva from a tree.""
