The United States says it will support a European proposal to offer Iran limited economic incentives in exchange for its abandoning nuclear enrichment activities. Secretary of State Condoleezza Rice announced the policy shift on Friday. She said Washington would drop its objections to Iran's application to the World Trade Organization and to the licensing of spare parts for Iranian civilian aircraft. She said the move shows American support for European efforts to secure Iran's nuclear cooperation through diplomatic means. President Bush later said he is pleased that the United States and Europe are, in his words, "speaking with one voice" on Iran. Earlier on Friday, Britain, France and Germany told the European Union that they would support bringing Iran before the U.N. Security Council if talks fail to persuade Iran to permanently stop enriching uranium.
