(CNN) -- The people who killed three Israeli teenagers have hurt the Israeli people deeply, there's no doubt about that. But they have also harmed Palestinians, and they have hurt the cause of peace. Anyone who fails to condemn this horrific act -- the murder of students going home from school -- is contributing to the poison that makes peace so difficult in the Mideast. Anyone who hesitates, who equivocates, is helping to prolong the conflict. For Palestinians and their supporters around the world, if you remain silent about the killing of Israelis, you are adding to the duration and bitterness of this conflict. Excuse this atrocity, and you condemn the people of this area to remain enemies for the foreseeable future.
