Iran's president has sent President Bush a letter proposing "new solutions" for getting out of "international problems and the current fragile situation of the world."
An Iranian spokesman says President Mahmoud Ahmadinejad did not mention Iran's nuclear program. That's the major issue on which Washington and Tehran disagree.
The US and European nations are trying to persuade Iran to stop uranium enrichment and have brought the dispute to the UN Security
Council. Iran says its nuclear program is peaceful but the US fears Tehran wants atomic weapons.
Yesterday, Ahmadinejad renewed Iran's threat to withdraw from the Nuclear Nonproliferation Treaty if the UN Security Council imposes sanctions.
The letter is the first in 27 years that an Iranian president has sent to a US president. The US hasn't had diplomatic relations with Iran since the 1979 hostage crisis.
