Now, the West is trying to prevent Iran from mastering nuclear technology, even though Iran is a member of the NPT. They voice their concern claiming that Iran's intention is to develop nuclear weapons. The International Atomic Energy Agency (IAEA) has reported numerous times that there is no evidence that Iran is developing nuclear weapons, however, it also says that it can not say for sure that Iran is not doing so in secret. A CIA report on nuclear activity in Iran, in December 2007 claimed that Iran's secret program to achieve nuclear weapons technology was stopped in 2003, and that since then, it was never restarted. It reports that Iran's ability to build a nuclear weapon will probably not happen soon.
