Another session of talks with Iran is scheduled to take place next month, probably in Turkey. But at a conference on Friday held by the Foundation for the Defense of Democracies, Mr. Obama’s coordinator for weapons of mass destruction, Gary Samore, suggested that Iran may have decided to resume talks with the with the members of the United Nations Security Council and Germany “because it believes it can manipulate the appearance of negotiations to weaken existing sanctions and avoid additional measures.”
“This ploy will not work,” Mr. Samore said. “In the wake of the Geneva talks, we and our allies are determined to maintain and even increase pressure. We need to send the message to Iran that sanctions will only increase if Iran avoids serious negotiations and will not be lifted until our concerns are fully addressed.”
Mr. Samore was not specific about the sanctions now being contemplated. He also would not comment on the effects of the Stuxnet worm, which appears to have been directed at disrupting Iran’s centrifuges.
“I’m glad to hear they are having troubles with their centrifuge machines,” he said with a smile, “and the U.S. and its allies are doing everything we can to make it more complicated.” But he said nothing about who was responsible for the worm.
