When Iran and Israel were friendly
The alliance, though never formalized or publicized because of Israel’s unpopularity in the region, consisted of deep intelligence and arms cooperation, as well as oil sharing. In the late 1950s, Israel, Iran and Turkey formed a trilateral intelligence alliance and performed counterterrorism intelligence operations. In the early 1960s, they teamed up to support Iraqi Kurds fighting the central regime. According to Kaye’s research, “Tehran and Tel Aviv developed a close military and intelligence relationship that would continue to expand until the Islamic revolution.”
