But the Bedouin who used to pass, listlessly urging their camels between the dunes, had taken the news of the cranes and bulldozers and cement-making apparatus across the border to the military governor of the Egyptian town of El Arish. The message had gone to Cairo of huge construction works deep in the Negev desert, of wire fences sprouting up, of armed troops patrolling. The concern in Cairo was passed to the American State Department in Washington. There, too, anxiety was expressed and the foolproof system of international espionage set in motion.
From a United States Air Force base in northern Iran a U2 plane had taken off with orders to fly over Dimona and photograph the new complex. The pilot had violated Israeli air space at an altitude of fractionally more than fifteen miles. At the IAF field which had specific responsibility for Dimona they could only watch the radar blip of the American reconnaissance aircraft and contain the frustration that it was beyond their own operational ceiling. It had been a brilliantly hot October day, back in 1960, when the photographs were taken. Sokarev had been working in his temporary, prefabricated wooden offices, awaiting the fulfilment of the Director's promise that he was high on the list for more suitable and permanent premises. He, like everyone else who pored over charts and diagrams and formulae, was unaware of the pictures being recorded in the upper stratosphere.
After the Uz landed in Turkey the rolls of film were rushed under conditions of great secrecy direct from the cameras in the plane's nose to another aircraft standing ready and fuelled to fly to Washington. They showed the little wooden hut where Sokarev worked – or at least its roof – but there was small interest in that compared with the bulky shape discernible a hundred yards away across the sand and surrounded by the lorries that were needed to bring up the materials. The men expert in interpreting altitude photography identified a medium-sized nuclear reactor, the integral plant necessary in the manufacture of the plutonium that is at the heart of an atomic explosion.
When Dimona was washed out into the open the news made slight adjustments to Sokarev's life. The degree of security that had wrapped round the very existence of the project was relaxed. The Israeli Government issued statements about the requirement for nuclear energy for peace-ful uses, ranging from electricity power to the extended life of vegetables on shop counters. Sokarev was pleased.
Fewer of his friends regarded him with such curiosity. Life became more normal.
In the halcyon days after the June victory of 1967, when the nation's defences seemed secure and the Arabs had taken a bloodied, broken nose, been pushed back far from the Israeli settlements, across the great buffer zones of Sinai, the Jordan valley, and the Golan Heights, then there was little to concern Sokarev about the pace of his work.
He was at forty-one a young man for his job, on the up, regarded by his colleagues as brilliant and directing his energies toward what his project director blithely called the 'agro-nuclear complexes': the reclaiming of desert land through the use of thousands of millions of gallons of sea water, distilled through nuclear power. The project did not last.
The war of attrition across the Suez water-way exacted a toll both from human life and from the fragile Israeli economy. New tensions rose along the Egyptian and Syrian borders. And on the day in October 1973 when Sokarev and his family were at prayer, Yom Kippur Day, the Arab armies breached the great defensive lines that lay along the Canal and which bestrode the Golan. The peace was hard-won this time; none of the trumpeting of 1967 followed the cease-fire. Reports filtered through the foreign press of new, far-reaching Soviet rockets, sited on the plains behind Damascus and protected by nests of anti-aircraft missiles, rockets that could reach any Israeli town, either with a conventional high-explosive warhead or armed with a localized nuclear device. To Sokarev and to many of his team it was clear the time had come to consider intensely, if perhaps belatedly, what was called in the common rooms round the world where men specialized in physics, the
'nuclear option'.
The days at Dimona started earlier, ended later. Sokarev and the team that was built around him wrestled with the problems of abbreviations in time and expenditure for the fashioning of the bomb. Extraction of uranium from the phosphate ores of the Negev was increased, as the plant gulped up more than twenty-five tons a year. Some of the ablest men in the department were sent to the United States, and then to West Germany to study at the European nuclear centre. As a result the costly Jericho missile system was developed with a range of more than three hundred miles, the country's own and independent delivery weapon.
