"But the revolution has turned Egypt inward, ushering in a transitional government that is more concerned with the approval of its own citizens than the security of Israel, or even the threat of subversion. Egypt’s new leaders have unnerved Israel by cultivating closer ties with Hamas and Iran. And while they have focused on securing Cairo, they have allowed the northern Sinai region along the Israeli border to slide into lawlessness, leaving Bedouin tribes to keep the peace. The smuggling of goods and migrants has surged through a network of tunnels under the Gaza border. Egypt was forced to take action recently to restore order after a police station in the regional capital of Arish was attacked by what the authorities said were Islamist militants. In the last few days, the Egyptian military has sent more than 1,000 troops to the area to apprehend the suspects."
