John Scarlett’s continued refusal to withdraw the team had led to an increasing coldness in Mossad’s relationship with MI6. While important intelligence passed between both services on the usual need-to-know basis, Nathan, the London station chief, no longer took a regular cab ride from the Israeli Embassy in Kensington to the glass-faced building overlooking the river Thames, known as “the wedding cake” for its tiered shape, to share a convivial hour with senior MI6 officers over drinks and sandwiches. The occasions were a chance to get to know the thinking within MI6 on a wide variety of issues, and there were lively discussions on what one MI6 officer had called “the current state of play” in Damascus, Riyadh, and Egypt. In that closed world in the hospitality suite on the fifth floor, what was not said was often as important as what was said. Scarlett had sometimes dropped in on those gatherings to inquire how things were in Tel Aviv.
But until the “Gaza business” was settled, contacts with MI6 were to be confined to essentials. Mossad’s mood had not improved when Nathan’s MI6 liaison officer had said that the Hamas team believed it was making good progress in persuading Hezbollah to end its attacks on Israel.
But for the moment the stand-off with London was of less importance than the reason for the meeting. For the men around the conference table, who had helped Israel to survive war and Intifadas, the high-resolution satellite photographs spread before them told a grim story. The images were of Iran’s nuclear facilities filmed only a week before by Israel’s own satellite. They showed the six prime plants that were scattered across the country. Each facility was buried under thousands of tons of reinforced concrete, hard to penetrate with even the BLU-109 “bunker buster” bombs the United States had recently sold to Israel.
Accompanying the images were reports from Mossad’s deep-penetration agents in the country. Their identities were a closely guarded secret between Dagan and his assistant director on the seventh floor of the headquarters building. One agent had revealed that the Natanz facility in southern Iran was working around the clock to enable its fifty thousand centrifuges to eventually produce huge quantities of enriched uranium in its three heavily fortified underground structures. Another report demonstrated how Russia had provided 150 technicians to upgrade the Bushehr nuclear power plant on the Persian Gulf, severely damaged in Iran’s war with Iraq. A third report described the installation at the Sharif University of Technology of centrifuges capable of running a uranium-enrichment program. Yet another report highlighted the capability of the University of Tehran’s nuclear reactor to come on stream in Iran’s drive to build a nuclear bomb. One agent had pinpointed the entrances to underground facilities in the desert fastness of Yazd Province. The most detailed report described a plant on the outskirts of the ancient city of Esfahan. Sited close to the eastern suburbs, the cluster of modern buildings were near the towering Emam mosque and the magnificent eleventh-century bridge over the Zadaneh Rud River along which the carpet weavers of Esfahan have exported their wares for a millennium.
The men around the conference table saw the area around the uranium conversion facility had been recently reinforced, making it the most heavily guarded of all the facilities. A defense perimeter of antiaircraft guns, razor wire, and thousands of heavily armed soldiers now surrounded the plant hewn into a hill. It was its capability to enrich uranium hexafluoride (UF6) gas that was reason enough for Israel’s intelligence community to assemble in the room. The Mossad agent’s report had ended with the revelation that Esfahan’s uranium conversion facility had already produced three tons of UF6 gas. This was sufficient to enrich uranium for civilian nuclear power—which Iran claimed it would be used for—or for the fifty thousand centrifuges at Natanz ninety miles to the northwest to produce a nuclear weapon.
The agent’s report listed other sites where missile production was underway. The largest was Darkhovin, south of the city of Ahvaz. The facility was heavily fortified with two battalions of the Revolutionary Guard. It employed three thousand scientists and engineers. Most of their work was underground building rocket motors. Mu-allimn Kalayeh was sited in the mountains near Qasvin, its uranium enrichment gas centrifuges produced the enriched weapons-grade material for warheads. Saghand was in the remote desert east of Tehran. It employed eight hundred technicians building casings for the rockets. Nekka, near the Caspian Sea, was buried underground; the complex employed over a thousand scientists. Its facilities included a Neutron Source Reactor purchased from North Korea.
