IN the United States and in Europe, there is a widespread belief that the Bush administration has failed to engage Iran diplomatically. Among the advisers to the Iraq Study Group, of which I was one, most believed that the Bush administration, not the mullahs’ regime, was the most culpable party in foreclosing dialogue between Washington and Tehran after 9/11.

Iran’s American-educated longtime ambassador to the United Nations, Javad Zarif, has tirelessly suggested that the administration missed opportunities for improving relations and is tone-deaf to his country’s peaceful intentions.

Yet it ought to be clear that just the opposite is the case. The clerical regime today is no more interested in reaching a peaceful modus vivendi with the United States than it was in the 1990s, when President Bill Clinton and Secretary of State Madeleine Albright all but begged President Mohammad Khatami of Iran to just talk to them.
