"Although President Bush has said that no option is off the table, I don't think a U.S. attack on Iran is likely," stated to Turkish Daily News Matthew Bryza, the Deputy Assistant Secretary of State for European and Eurasian Affairs. In his words, U.S. policy is to change the behavior of the Iranian government through diplomacy. "We are not speaking about changing the regime. We will carry out our policy through the U.N. and beyond the UN," Bryza stressed.
