The President of Iran, Mahmoud Ahmadinejad, warned the U.S. and its allies to abandon what he called "arrogant policies." Ahmadinejad also seemed to dismiss any idea that his country would use its nuclear activities to build weapons. That is exactly what the United Nations and others fear most. But Tuesday Ahmadinejad asked the rhetorical question, "What is an atomic bomb good for?" He went on to say, "Thoughts can't be changed by a nuclear bomb. Today is the day of thought and logic."
