Following yesterday's display of its nuclear prowess, Iran says it's ready to resume talks over its nuclear program. In a letter to the European Union obtained by CNN, Mahmoud Ahmadinejad proposed re-starting the talks as soon as possible. Yesterday, the country showed off new centrifuges, with the president visiting a Tehran reactor to install fuel rods. Iran announced it would start making its own yellowcake, which the UN has banned it from importing; it also said it would share its nuclear knowledge with other countries overseen by the International Atomic Energy Agency.
