U.S. National Security Adviser Stephen Hadley visited Moscow Monday. Hadley met with Foreign Minister Sergey Lavrov and other senior officials at the start of his two-day visit. The United States has been trying to rally support for bringing Iran before the U.N. Security Council for possible economic penalties if it does not provide answers and allay fears about its nuclear program. "We are conducting a wide discussion with Russia on this topic," Hadley was quoted as saying by the ITAR-Tass news agency before his meeting with Lavrov. "Our positions are similar, and we are agreed on the basic points," he said.
