A visiting US senator said on Monday that there was little difference between the policies of President Barack Obama and his predecessor over Iran - both want to keep Iran from getting nuclear weapons. Sen. Benjamin Cardin, a Democrat from Maryland, said that Obama agrees with George W. Bush: "Iran's got to stop financing terrorist activity. Iran's got to give up its desire to become a nuclear weapons power. Its as clear as that." Obama has indicated a willingness to negotiate with Iran, while Bush resisted talks. Cardin said Obama could use his international goodwill to try to make progress in the Israel-Palestinian conflict. Cardin is leading a fact-finding mission to Israel and Syria. He said he was not asked to carry a message from Israel to Syria.
