Quoted: Olli Heinonen, Belfer Center senior fellow
“Olli Heinonen, a former deputy director general of the IAEA, said Iran may lack the precision engineering capabilities needed to build a working bomb. In theory, however, Iran could secretly construct a bomb or warhead, a process likely to take several years, and then produce weapons-grade fuel in a month or so.
‘You can build everything else, but you just leave the nuclear material out and do that at the end,’ said Heinonen, now a senior fellow at the Belfer Center for Science and International Affairs at Harvard University.”
