Iranian President Mahmoud Ahmadinejad will speak in the coming days at the U.N. General Assembly in New York, where he will preach his hatred of the United States, the West and Israel. The backdrop of his speech is the looming likelihood of Iran becoming a nuclear power. The Obama administration, in concert with U.S. allies, must intensify its efforts at the United Nations to bring further sanctions against the theocratic rulers of Tehran to maximize the prospect of a peaceful resolution and to prevent the regional and global destabilization that would come with an Iranian nuclear arsenal.

According to a recent U.N. inspection report, Iran is steadily stockpiling enriched uranium, even amid toughened international sanctions. This report raises new worries that Iran's nuclear program cannot be adequately monitored. The International Atomic Energy Agency said that it cannot confirm quantities of certain nuclear materials and has a growing list of questions about enrichment sites. Iran recently decided to eject two IAEA inspectors.
