Mossad

Last week's arrests of a dozen alleged CIA agents in Iran threw a spotlight on long-standing, covert U.S.-Israeli actions in the Islamic republic -- including purported involvement by the CIA and Mossad in the recent killings of Iranian nuclear scientists. Though enduring, the collaboration between Western and Israeli intelligence agencies in intelligence and assassination operations reveals a relationship of cooperation and distrust.

The Mossad (Hebrew for "institution") is Israel's main intelligence agency. According to the Global Security site, Mossad also oversees "covert action and counterterrorism"; its operations are widely held to include targeted killings. At the time of its founding, the Mossad's motto was the biblical quote "By way of deception thou shalt make war." The motto was later changed to a different Proverbs passage: "Where no counsel is, the people fall, but in the multitude of counselors there is safety." Sources refer variously to the Mossad's international assassination unit as "Metsada," "Caesarea," or "Kidon" ("Kidon" is Hebrew for "bayonet"). Rafi Eitan, a former director of Mossad operations, compared its assassins to "the official hangman or the doctor on Death Row who administers the lethal injection. We are simply fulfilling a sentence sanctioned by the prime minister of the day."
