ran unveiled a third generation of domestically built centrifuges on April 9, which officials said would enrich uranium much faster than existing models. US President Barack Obama, who is seeking tougher UN sanctions against Tehran, acknowledged that such measures would not necessarily work, but said sustained world pressure could overtime prompt Iran to revise its nuclear calculations. During a ceremony marking Iran’s National Day of Nuclear Technology, President Mahmoud Ahmadinejad pulled back a white curtain to reveal one of the tall, cylindrical machines to a crowd of assembled dignitaries. The display capped months of announcements about the development of the new machines. Ahmadinejad, in his speech, called the nuclear arms reduction treaty that Obama signed with Russia this week “a masquerade” hiding his true intentions.
