Iran's president on Tuesday dismissed a year-end deadline set by the Obama administration and the West for Tehran to accept a U.N.-drafted deal to swap enriched uranium for nuclear fuel, and claimed his government is now "10 times stronger" than a year ago. Mahmoud Ahmadinejad's remarks underscored Tehran's defiance amid the nuclear standoff and also sought to send a message that his government had not been weakened by the protest movement sparked by June's disputed presidential election. His comments came a day after the latest opposition protest by tens of thousands mourning a dissident cleric who died over the weekend. President Barack Obama has set a rough deadline of the end of this year for Iran to respond to an offer of dialogue and show that it will allay fears of weapons development.
