US silence; The truth about Israel's secret nuclear arsenal

Deep beneath desert sands, an embattled Middle Eastern state has built a covert nuclear bomb, using technology and materials provided by friendly powers or stolen by a clandestine network of agents. It is the stuff of pulp thrillers and the sort of narrative often used to characterise the worst fears about the Iranian nuclear programme. In reality, though, neither US nor British intelligence believe Tehran has decided to build a bomb, and Iran's atomic projects are under constant international monitoring.
