ithe ;New Uork times November 22, 2012 Factions in Gaza Make Unity Vow After Cease-Fire By JODI RUDOREN and ISABEL KERSHNER GAZA — Palestinians erupted in triumphant celebrations here on Thursday, vowing new unity among rival factions and a renewed commitment to the tactic of resistance, while Israel's leaders sought to soberly sell the achievements of their latest military operation to a domestic audience long skeptical of cease-fire deals like the one announced the night before. After eight days of intense Israeli shelling from air and sea that killed 162 Gazans, including at least 30 militant commanders, and flattened many government buildings and private homes, people poured onto the bomb-blasted streets, beaming as they shopped and strolled under the shield of the cease-fire agreement reached Wednesday in Cairo. The place was awash in flags, not only the signature green of the ruling Hamas party but also the yellow, black and red of rivals Fatah, Islamic Jihad and the Popular Front for the Liberation of Palestine, a rainbow not visible here in years. Despite the death and destruction, Hamas emerged emboldened, analysts said, not only because its rockets had landed near Tel Aviv and Jerusalem, but also from the visits and support by Arab and Muslim leaders, potentially resetting the balance of power and tone in Palestinian politics, as leaders from various factions declared the peace process dead. "The blood of Jabari united the people of the nation on the choice of jihad and resistance," Ismail Haniya, the Hamas prime minister, declared in a televised speech, referring to the commander Ahmed al-Jabari, killed in an Israeli airstrike at the beginning of the operation last week. "Resistance is the shortest way to liberate Palestine." There were neither celebrations nor significant protests across the border in Israel, where people in southern cities passed the first day in more than a week without constant sirens signaling incoming rockets
