I will analyze the last two sentences. The first sentence seems to me to be entirely confused. On the 7th of June 1981 eight Israeli planes destroyed to so-called Osirak reactor near Teheran. It had been sold to the Iraqis by the French and they named it. Os for the Osiris class and Irak for its destination.It was a small reactor compared say to a power reactor. It generated 40 megawatts of power whereas a power reactor generates a couple of billion. It was fueled by highly enriched uranium -93%-of the kind you would use in a weapon. At the time of the raid the French had supplied 12.5 kilograms. Not much less then you would need to make a bomb-about 16 kilograms. (The amount actually depends on the type of bomb but this gives the order of magnitude.)The Israelis did not seem to pay any attention to this. They were concerned about the reactor’s capacity to produce plutonium like their own Dimona reactor. But the Osirak reactor was about as poorly designed for making plutonium as one could imagine. To make plutonium you want the least enriched uranium as possible. It is a reaction in which the common isotope U-238 absorbs a neutron which leads to plutonium.
This reactor could produce about .07 kilograms a year. Hence it would take centuries to produce enough to make a bomb which requires about ten kilograms. Thus from the point of view of proliferation the Israeli raid was less than useless.It left the Iraqis with a substantial amount of weapons grade uranium and inspired them to begin a uranium enrichment program. A.Q.Khan tried to sell his centrifuge package to Saddam Hussein but Hussein did not trust him. Rafsanjani discusses an unsuccessful trip to Pakistan to see A.Q.Khan to acquire nuclear technology. He does not give the date of this trip but starting in 1987 and lasting for nearly a decade Khan sold this material to Iran. The Iraqi’s never got far with their enrichment program.
Jeremy Bernstein is best known for his popular science writing and profiles of scientists. He was a staff writer for The New Yorker from 1961 to 1995 and authored many dozens of articles. He has also written regularly for The Atlantic Monthly, the New York Review of Books, and Scientific American, among others. His books include "Physicists on Wall Street and Other Essays on Science and Society" (2010), "Nuclear Weapons: What You Need to Know" (2010), "Quantum Leaps" (2009), "Hitler's Uranium Club: The Secret Recordings at Farm Hall" (2000), "In the Himalayas: Journeys through Nepal, Tibet, and Bhutan" (1996), and others, more than 15 books in all. "The Life It Brings", an autobiographical memoir, was published in 1986. Bernstein's biographical profiles of physicists, including Robert Oppenheimer, Hans Bethe, Albert Einstein and others, are able to draw on the experiences of personal acquaintance.
