Lack of American Support for Syrian Rebels Could Help Nuke Talks With Iran

Tehran still supporting Assad

WASHINGTON—President Barack Obama's reluctance to give military aid to Syrian rebels may be simply explained in part in three words: Iranian nuclear weapons.

For the first time in years, the United States has seen a glimmer of hope in persuading Iran to curb its nuclear enrichment program so it cannot quickly or easily make an atomic bomb. Negotiations resume this week in Almaty, Kazakhstan, where encouraging talks in February between six world powers and the Islamic Republic ended in what Iranian diplomat Saeed Jalili called a "turning point" after multiple thwarted steps toward a breakthrough.
