In 1969, the Central Intelligence Agency decided it should cultivate a relationship with the Palestine Liberation Organization (PLO)—then designated a terrorist organization by the U.S.—with the goal of wooing Yasir Arafat away from the Soviets. Arafat, writes Sean Durns, played along:

To facilitate this relationship, Arafat relied on Ali Hassan Salameh, the head of Force 17, his personal security force and counterintelligence unit. . . . A flamboyant womanizer, [Salameh] wore leather jackets, drank alcohol, and practiced karate. His father, Hassan Salameh, had been a famous Palestinian terrorist who took part in, among other acts, a failed Nazi plot to poison Tel Aviv’s water supply during World War II. . . . The CIA told Salameh that he “has friends in high places and so does his cause.”

Salameh even admitted to his handler, Robert Ames, that he had recruited a Paris theater-owner who had sent agents to blow up a hotel in Israel.

Neither this information, nor the PLO’s murder of two American diplomats in Khartoum in February 1973, dissuaded the CIA from maintaining the relationship. In fact, terrorism seemed to have had the opposite effect: in November of the same year, the Agency formalized its relationship with the PLO and, in 1976, then-CIA director George H.W. Bush invited Salameh to visit headquarters in Langley, Virginia.

During his January 1977 visit to Langley, a CIA operations officer named Alan Wolfe gave Salameh—whom Israelis held responsible for helping plan the 1972 Munich Olympic Games massacre in which eleven Israeli athletes were held hostage, tortured, and murdered—a leather shoulder holster for his gun. Perhaps most incredibly, at his request, the CIA subsequently took Salameh and his wife to Disneyland for their honeymoon, accompanying him on the rides and paying for the trip.

Salameh’s initial CIA contact, Robert Ames, would be murdered, along with 62 others, in an April 18, 1983 suicide car bombing at the U.S. embassy in Beirut. The attack was carried out by Shiite jihadists and reportedly planned by Imad Mughniyeh, formerly an operative of Salameh’s Force 17.

As for Salameh himself, the Mossad assassinated him in 1979. Another CIA officer sent his son a condolence letter.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
