For more than two years, unmarked Israeli drones, helicopters and jets conducted over 100 air strikes against Islamist terrorists in Sinai, with the approval of Egyptian President Abdel Fatteh el-Sisi. The New York Times cites seven British and US anonymous sources on this. They report that the secret cooperation between the two former enemies helped the Egyptian military regain its footing after nearly five years of battling the jihadists. For Israel, the strikes have bolstered the security of its borders and the stability of its neighbor and opened the door to Israeli-Arab relations on a new footing. Israeli and Egyptian spokesmen declined to comment in the report.
