Attaining nuclear weapons will not further the Iranian cause, President Shimon Peres said on Tuesday. Speaking during an official visit to the northern city of Sakhnin to mark the Muslim holiday of Eid al-Adha, Peres said, "[Iranian President Mahmoud] Ahmadinejad needs to wake up tomorrow morning and give food to Iranian children. What will he give them to eat? Enriched uranium?" "Iran needs to understand that the path of nuclear weapons and war will bring only harm," he added. Captured IDF soldier Gilad Schalit's grandfather, Zvi Schalit, was present at the event, and the president addressed him directly, saying, "I pray that you will be able to celebrate this coming holiday of Chanukah already with your grandson, Gilad. The responsibility remains upon all of us to return Gilad home." Before being thanked by Sakhnin Mayor Mazen Genaim, Peres gave a traditional holiday blessing, in Arabic, and urged Muslims worldwide to work together to achieve peace and reconciliation between all peoples. "Indeed there were wars with Egypt and Jordan, and we nonetheless made peace with them. We left Lebanon and we left Gaza. These were steps that took time, and we cannot take too much more time to arrive at a comprehensive peace agreement with the whole Middle East," he said.
