Iran’s Strategic Nuclear Dilemma
Sima Shine
INSS Insight No. 2025, August 14, 2025
Two central pillars of Iran’s security perception have been undermined since its war with Israel: First, its nuclear program has suffered a severe blow, and second, the “resistance camp” of its regional proxies has been weakened to the point that, for now, it cannot stand by Iran’s side. Tehran must now formulate its nuclear policy under intense time pressure—caught between President Trump’s ultimatum and the threat from the European countries (the E3) to renew the UN Security Council sanctions by activating the “snapback” clause....
The war between Israel and Iran, known as Operation Rising Lion, significantly set back Iran’s nuclear program. Iran is no longer a nuclear threshold state as its status was prior to its war with Israel. It would take Iran at least one to two years to regain threshold status, assuming a decision by Supreme Leader Khamenei to pursue nuclear weapons. However, the war did not eliminate Iran’s nuclear capabilities entirely. Iran maintains residual capabilities that could eventually enable the rebuilding of its nuclear program and the...
Operation Rising Lion: Achievements, Open Questions, and Future Scenarios

INSS Insight No. 2007, July 9, 2025
Operation Rising Lion, carried out on Iranian soil was a highly significant campaign, showcasing operational artistry, excellence, and a sophisticated, complementary international diplomatic effort. Whereas gratification is in order, the campaign must be analyzed objectively and professionally. Were its goals truly achieved? Has an existential threat to the State of Israel been removed? Has Israel’s security situation improved meaningfully or is it caught in a vicious circle of tactical excellence and strategic failure?
Although it...
The Israel–Iran War: Concluded but not Resolved

INSS Insight No. 1998, June 25, 2025
The fragile ceasefire between Iran and Israel marks the end of the current—and thus far most severe—phase in the ongoing hostilities between the Islamic Republic and Israel. Israel can conclude this phase of the conflict with a degree of satisfaction: even if Iran still retains a stockpile of uranium enriched to 60%—which it possessed before the campaign and may have transferred to hidden locations—its nuclear program has been significantly set back. Conversely, Iran is expected to portray the battle as a success, regardless of its...

The Campaign against Iran: Situation Assessment, Dilemmas, and Implications
Raz Zimmt
INSS Insight No. 1996, June 17, 2025
Three days into the campaign between Israel and Iran, Tehran is approaching a crossroads regarding the continuation of hostilities, a potential exit strategy, and a possible post-conflict arrangement. For now, Iran remains focused on managing the war. However, as the campaign continues and the damage accumulates, Tehran will need to choose between maintaining the current level of confrontation, ending the fighting through a political arrangement, or escalating further—potentially by withdrawing from the Non-Proliferation Treaty...

The International Atomic Energy Agency (IAEA) published two alarming reports regarding Iran’s nuclear program. One report addresses Iran’s past activities at sites not declared to the IAEA, for which Tehran has failed to provide satisfactory explanations. The second report concerns the current status of the program and indicates an acceleration in the accumulation of highly enriched uranium, enabling Iran to enrich to military grade for 10 nuclear bombs within days. Both reports are expected to be discussed at the upcoming IAEA Board...
Iran—Between Accepting a Diplomatic Settlement or Acquiring a Nuclear Bomb

INSS Insight No. 1949, February 19, 2025
As the renewal of nuclear talks approaches, the Iranian leadership faces an increasingly sharp dilemma over the strategy it should adopt regarding its nuclear program. On one side, figures from the “moderate” camp are urging Tehran’s leadership to take a conciliatory approach that would lead to a nuclear agreement with the United States in exchange for concessions on its uranium enrichment program. On the other side, voices within the “conservative” camp are growing louder, advocating for Iran to reconsider its nuclear strategy and...
Toward Possible Changes in Iran’s Security Concept
Raz Zimmt
INSS Insight No. 1915, November 18, 2024
Regional developments are posing challenges to Iran and the pro-Iranian axis it leads, raising doubts about the effectiveness of the main elements of its deterrence against its enemies. These elements include Iran’s use of “proxies,” its strategic military capabilities (missiles and drones), and its nuclear program. Recent months have revealed shortcomings in Iran’s security concept, which could lead to different approaches among the Iranian leadership. This may result in limited adjustments or a more strategic shift, especially...
The election of Donald Trump to the US presidency represents a particularly concerning scenario for Tehran. Despite initial attempts by Iranian official to downplay this development, it is clear that Iran is highly apprehensive about the election results, especially given reports that it had attempted to assassinate Trump and his hawkish stance toward Iran during his first term. Furthermore, Trump’s return to office finds Iran at a critical crossroads. In the short term, it must decide on the timing and nature of its response to...
In the ongoing conflict between Iran and the International Atomic Energy Agency (IAEA) and following a resolution condemning Iran’s lack of cooperation with the agency, Tehran announced an increase in the number of centrifuges enriching uranium at the Fordow and Natanz sites, effectively declaring its intention to increase its stockpile of enriched uranium. With the current quantities, Iran could, within a month of making a decision, begin enriching to military levels and produce enough enriched material for eight nuclear devices....
