Our efforts to stop Iran from getting a nuclear weapon seem to be in tatters. President Obama spent his first year in office trying to resolve the matter through détente. He offered negotiations, sent a conciliatory letter to Iran's supreme leader, and was slow to publicly support the demonstrations that followed the June 2009 elections. Last fall, the United States sponsored an International Atomic Energy Agency (IAEA) deal through which Tehran would have been able to swap out its dangerous spent fuel for uranium suitable to be used in power generation. But this outreach was spurned, and Iran's nuclear program continued.
