Israel and Gaza’s leaders are locked in talks to harden the temporary ceasefire that halted last month’s hostilities, but prospects for a longer peace hinge largely on Egypt, and whether its new Islamist government has the will and strength amid domestic unrest to control weapons flowing through an increasingly unruly Sinai Desert, The Wall Street Journal reported Monday, December 3. Most of the weapons wielded by Gaza’s terrorist groups are transported across the Sinai Peninsula and smuggled into Gaza through a network of tunnels. A recent smuggling surge helped Gazan terrorists obtain new advanced weaponry, including Iranian-designed Fajr-5 rockets that targeted Tel Aviv and Jerusalem. Egypt, under newly elected President Mohammed Morsi, has seized arms in the Sinai and filled in alleged smuggling tunnels. But critics say Cairo’s latest efforts have largely been public-relations moves that haven’t effectively cut off flows to Gaza.
