Iran Primer: The Politics of Iran's Nuclear Program
International tension over Iran’s nuclear ambitions has turned the nuclear program into a major domestic political issue and has caused conflict between the regime and conservatives as well as the opposition.

Iran’s nuclear weapons program was part of a broader attempt to become more self-reliant in arms and technology in the 1980s. Increasingly isolated, Tehran struggled to acquire arms to fight Iraq, which used chemical weapons and had a nuclear weapons program. The eight-year war was the Middle East’s bloodiest modern conflict. Iran’s nuclear program was an outgrowth of this experience.
Iran’s nuclear program unfolded in context of its overall politics. Since the 1979 revolution, Iran’s political elite has long been divided over how the theocracy should evolve and what international role it should pursue. Beyond broad concepts, such as independence, self-reliance and social justice, consensus has proven elusive—even three decades after the Islamic Republic’s birth. The most fundament difference is whether Iran should continue as a revolutionary state willing to defy the world, or whether it should settle down and become a normal state that plays by international rules. The nuclear issue is increasingly a reflection of this basic division.
The nuclear program has evolved through three phases.
Iran’s nuclear program became increasingly political during this phase. As of 2005, both the executive branch and parliament were dominated by hardliners and conservatives. Both Ahmadinejad and Supreme Leader Ayatollah Ali Khamenei used the nuclear issue to stigmatize reformists, depicting them as defeatists willing to negotiate away Iran’s interests. Their use of the nuclear issue as an instrument of partisan politics ended the phase when the nuclear program was supposed to be a national issue. And debate was actively discouraged.
- Iran envisages an energy program that encompasses 10 to 12 reactors generating some 24,000 megawatts and several enrichment plants. It is also building a heavy-water plant at Arak, a source of proliferation concern.
- Bushehr’s 1,000 megawatt light-water reactor was built by Russia and took 15 years to complete. The deal stipulates that fuel is provided by Russia and the spent fuel rods will return to Russia.
- The average reactor takes at least a decade to construct and a minimum of $1 billion before start-up, with costs likely to increase with inflation and international sanctions.
- Even with its own enrichment capability, Iran may lack sufficient indigenous sources of uranium ore.
Akbar Hashemi Rafsanjani is a two-time president and veteran political operative who was in charge of Iran’s defense when the decision to revive the nuclear program was taken in the 1980s. He has alluded to the need for Iran to be prepared for the unexpected in defense matters, and most likely led the decision to hedge by seeking a weapons option. Known as a leading pragmatist, he is personally opposed to Ahmadinejad, whom he ran against for president in 2005. On the nuclear issue, he is more likely to seek a pragmatic accommodation with the world than to accelerate enrichment.
Mir Hossein Mousavi was prime minister during the Iran-Iraq War. Considered a radical supporter of the revolution at the time, he would have been privy to and may have strongly supported the revival of the nuclear program, including a weapons option. Mousavi reflects the evolution of first generation of revolutionaries. Now more pragmatic, he is also more disillusioned by the tendency toward authoritarianism and praetorianism, the control of society by force or fraud. He leads the Green Movement opposition, and straddles the rift between those who feel the regime can be reformed and those who feel it needs to be replaced. On the nuclear issue, he has suggested a reasonable accommodation with the international community.
Moshen Rezaie was the Revolutionary Guards commander during the Iran-Iraq War and is known to have told Rafsanjani that Iran could not pursue the war with Iraq to victory without a nuclear weapon. He is now considered a “pragmatic conservative,” and was a presidential candidate in 2009. He suggested an “international consortium” as a possible compromise solution on the enrichment issue. All three of the opposition presidential candidates – Mousavi, Rezaie and former Parliamentary Speaker Mehdi Karroubi – criticized Ahmadinejad’s nuclear policy as provocative and costly for Iran, despite the supreme leader’s explicit support of it.
Ali Larijani, parliamentary speaker and formerly chief nuclear negotiator (2005-2007), is ambitious and a political opportunist. Larijani started the factionalization of the nuclear issue by accusing the reformists of selling out Iran’s enrichment “pearl” for “candy.” He is a conservative but has also had disputes with Ahmadinejad.
- Support for Iran’s nuclear program, always vague, is likely to become even more politicized. The weapons component of the program has never been debated or acknowledged and further revelations or costs associated with it could make it more controversial. Since 2009, factions take positions that do not reflect their real preferences, mainly to thwart political rivals.
- Increased international pressure and sanctions are likely to increase the program’s costs, which is also likely to make the program more contentious at home – and potentially exacerbate existing political differences in the leadership.
- Iran’s hardline default position—to negotiate only under the most severe pressure—has been reinforced by the change in the domestic balance of power. The Revolutionary Guards are now a principal player in decision-making.
- A wild card is the possibility of an Israeli or U.S. military strike on Iran’s nuclear facilities; the repercussions are unpredictable. A reasonable assumption is that initially Iranians may rally around the flag and hardliners will try to further consolidate their position by purging the moderates. The regime will also see its rationale for a weapons option reinforced, and may shift to an overt weapons program and even leave the NPT. Once the dust settles, however, the domestic backlash to an attack may discredit the regime for its brinksmanship and intransigence.
- Iran’s technical progress is uneven and allows time for more diplomacy. Any compromise agreement will need to find a balance between not rewarding Iran’s confrontational policies while also meeting Tehran’s minimal political needs in order to win domestic support for an agreement. This may be harder than it sounds.
