On May 19, Iran's choice is simple: engagement or isolation.

After the nuclear deal, there are three possibilities for the future of U.S.-Iran relations.

In Tehran, domestic hardliners and moderates are debating the nuclear issue, and the future of Iranian foreign policy.

International and domestic politics make it increasingly likely that the Iran-P5+1 negotiations will fail.

The future of America’s standing as a great power depends on the choices it makes in dealing with Iran.

While Saeed Jalili appears the early frontrunner, the early chaos of Iran’s presidential elections underscores the unpredictability of the race.

The real roots of Iran’s nuclear program lie not in physics – but in Iran’s own sense of history.

Iran’s leaders see little domestic political benefit to giving into the demands of the U.S. and its partners over Tehran’s nuclear program. The calculation shows no signs of changing.

Hardliners in the U.S. and Israel seem to be shifting on Iran’s nuclear program. Is a breakthrough possible in the Baghdad talks?

There are increasing signs that a breakthrough over Iran’s nuclear program could be in reach. But don’t expect Barack Obama to clutch at it yet.

There’s much pessimism surrounding this week’s scheduled talks over Iran’s nuclear program. But a quid pro quo approach offers a solution.

If the West wants to turn the screws on Iran’s regime it must do more to ensure that it isn’t hurting the Iranian people.

Iran’s supreme leader has built much of his legitimacy around demonizing the United States. So what could he really offer in talks with the U.S.?

A cornered Iranian supreme leader might be tempted to boost his domestic standing by lashing out at Israel. Israel is ill-equipped to respond.

Last week’s assault on the British Embassy was unacceptable. But more sanctions are only going to embolden Iran’s ideologues.

The attack on the British Embassy in Iran was a troubling escalation. If the attack was ordered by the supreme leader’s son, it could be just the start.

The latest IAEA report on Iran’s nuclear program has strengthened the hand of those calling for tougher action. But the U.S. should open the diplomacy door wider.

Iran’s supreme leader has hinted that the country’s presidency could be eliminated. It’s a clear warning to Mahmoud Ahmadinejad.

The idea that the alleged Iranian plot to assassinate the Saudi ambassador went to the very top is fanciful, says Robert Dreyfuss. Still, it has almost certainly scuppered the prospects for talks.

Claims Iran was plotting to assassinate the Saudi Arabian ambassador on US soil are extraordinary. Would Iran’s leadership really have OK’d such a plot?

Tensions between the president and Supreme Leader Ayatollah Ali Khamenei have been bubbling to the surface. Ahmadinejad is running out of options.

Claims of witchcraft and sorcery, firings and reinstatements – who will win the battle of wills between the Supreme Leader and President Ahmadinejad?

A new US intelligence estimate shies from accusing Iran of restarting pursuit of a nuclear bomb. But Arab world unrest has strengthened its hand.

Obama’s reelection and signs of Iranian willingness to end the nuclear standoff might offer some hope towards a compromise.
