According to this article in the New Yorker, Israel is operating hundreds of Mossad agents within the Kurdish areas of Northern Iraq. The hope being to have influence with the Kurds in the likely event that they seek greater autonomy or independence. This is due to their outlook on the future of Iraq:
The former Israeli intelligence officer acknowledged that since late last year Israel has been training Kurdish commando units to operate in the same manner and with the same effectiveness as Israel’s most secretive commando units, the Mistaravim. The initial goal of the Israeli assistance to the Kurds, the former officer said, was to allow them to do what American commando units had been unable to do; penetrate, gather intelligence on, and then kill off the leadership of the Shiite and Sunni insurgencies in Iraq. (I was unable to learn whether any such mission had yet taken place.) “The feeling was that this was a more effective way to get at the insurgency,” the former officer said. “But the growing Kurdish-Israeli relationship began upsetting the Turks no end. Their issue is that the very same Kurdish commandos trained for Iraq could infiltrate and attack in Turkey.”
The Kurdish-Israeli collaboration inevitably expanded, the Israeli said. Some Israeli operatives have crossed the border into Iran, accompanied by Kurdish commandos, to install sensors and other sensitive devices that primarily target suspected Iranian nuclear facilities. The former officer said, “Look, Israel has always supported the Kurds in a Machiavellian way; as balance against Saddam. It’s Realpolitik.” He added, “By aligning with the Kurds, Israel gains eyes and ears in Iran, Iraq, and Syria.” He went on, “What Israel was doing with the Kurds was not so unacceptable in the Bush Administration.”
