In The Washington Post former US weapons inspector David Kay compares the debate about Iran's nuclear program with the debate about Iraq before the war:
Vice President Cheney is giving interviews and speeches that paint a stark picture of a soon-to-be-nuclear-armed Iran and declaring that this is something the Bush administration will not tolerate. Iranian exiles are providing the press and governments with a steady stream of new "evidence" concerning Iran's nuclear weapons activities. (...) U.S. allies, while saying they share the concern over Iran's nuclear ambitions, remain determined to pursue diplomacy and say they cannot conceive of any circumstance that would lead them to use military force. And the press is beginning to uncover U.S. moves that seem designed to lay the basis for military action against Iran. Now is the time to pause and recall what went wrong with the assessment of Iraq's WMD program and try to avoid repeating those mistakes in Iran.
