All those American troops in Iraq, sure have managed not to intiminate Iran.
Iran's parliament unanimously approved the outline of a bill Sunday that would require the government to resume uranium enrichment, legislation likely to deepen an international dispute over Iran's nuclear activities.
Separately, Iran's top nuclear negotiator said there was a 50 percent chance of a nuclear compromise with European nations, though he ruled out an indefinite suspension of key enrichment activities.
Shouts of "Death to America!" rang out in the conservative-dominated parliament after lawmakers voted to advance the nation's nuclear program, an issue of national pride that provides a rare point of agreement between conservatives and reformers.
Washington has pushed hard for Iran to drop its nuclear program, which Tehran maintains is for peaceful energy purposes. The U.N. nuclear watchdog is also pushing for Iran to halt its activities.
The United States, which has secured some support from European nations, accuses Iran of trying to build nuclear weapons.
Parliament speaker Gholam Ali Haddad Adel called Sunday's vote a message to the world.
"The message of the absolute vote for the Iranian nation is that the parliament supports national interests," he said. "And the message for the outside world is that the parliament won't give in to coercion."
