This report looks at the background of Iran's nuclear policy. It covers the current status of Iran's nuclear facilities, and current controversy surrounding them, as well as the effects of international sanctions on Iran, recent sabotages on the Iran Enrichment Program, an estimated timeline of Iran's nuclear weapon capabilities, and whether or not Iran even has a nuclear weapons program.

With a conventional military and weapons of mass destruction (WMD) threat from Saddam Hussein's regime removed, Iran seeks to ensure that Iraq can never again become a threat to Iran, either with or without U.S. forces present in Iraq. By supporting armed Shiite factions, Iran's influence in Iraq has at times hindered U.S. efforts to stabilize Iraq, and has heightened the U.S. threat perception of Iran generally. However, Iran faces difficult choices in Iraq now that its protege Shiite factions, formerly united, are competing and often fighting each other.
