Concerns about the nuclear program of the Iranian regime have been a longstanding issue in Western foreign policy and in the Middle East region. After the National Council of Resistance of Iran (NCRI), an Iranian opposition coalition, revealed secret nuclear facilities in the early 2000s, the world became aware of the scope of the Iranian regime’s malign nuclear program. The United States withdrew from the nuclear agreement in 2018, and since then the Iranian regime has expanded its nuclear activities while international oversight has become more limited.
Following Israeli and U.S. strikes on nuclear facilities in 2025, satellite images show that the Iranian regime is rebuilding damaged sites. Negotiations between the United States and the Iranian regime were raised again in 2026, coinciding with a popular uprising in Iran. When nationwide anti-regime protests began in December 2025 and the authorities responded with severe repression, the United States once again considered military action.

Timeframe to Produce a Nuclear Weapon
The Iranian regime does not yet possess a nuclear weapon, but much of the necessary technical and industrial infrastructure for producing one is already in place. According to U.S. intelligence estimates, the Iranian regime could produce enough fissile material for a weapon within a few months. Some assessments put the time needed to produce the raw material at as little as one to two weeks, although converting that material into an operational warhead would require additional time.
The goal of the Joint Comprehensive Plan of Action (JCPOA), the 2015 nuclear deal between Iran and world powers, was to extend this breakout time to at least one year, giving governments time to respond. After the United States withdrew from the agreement in 2018, the Iranian regime increased enrichment levels and reduced access for inspectors from the International Atomic Energy Agency (IAEA). The last full inspections were carried out in 2021.
Rafael Grossi, Director General of the International Atomic Energy Agency, announced in December 2024 that the Iranian regime had increased uranium enrichment to about 60%, a level close to the 90% threshold required for nuclear weapons fuel. An IAEA report in May 2025 showed that the stockpile of near-weapons-grade uranium had increased by about 50% over several months, an amount that could be sufficient for approximately ten nuclear weapons.

U.S. intelligence in early 2025 also reported on the activity of a secret team of scientists pursuing a faster, albeit simpler, method of building a bomb. This increase in stockpiles and concerns about the shortening of the “nuclear breakout” time were cited as reasons for the U.S. strike on the Iranian regime’s nuclear facilities in 2025. Despite announcements that these facilities were destroyed, satellite imagery indicates that some are being rebuilt.
The Iranian regime conducts nuclear fuel cycle-related activities at more than ten sites across the country. The most important enrichment center is located in Natanz, which was damaged in the 2025 strikes. The country’s only nuclear power plant for electricity generation is located in Bushehr.
In a report in May 2025, the International Atomic Energy Agency stated that the Iranian regime had carried out undeclared nuclear activities at three previously unknown sites in Lavizan-Shian, Turquzabad, and Varamin, locations near Tehran. These reports have sustained doubts about the possible military dimensions of the program.
Military and Missile Capabilities
The Iranian regime possesses a diverse array of missile capabilities. U.S. intelligence analysts say the regime maintains the largest ballistic missile arsenal in the Middle East.
It has been reported that the Iranian regime’s long-range missiles are capable of reaching targets up to 2,000 kilometers or even farther, across the Middle East and parts of Europe.
In attacks in 2024, the Iranian regime directly targeted locations in Israel for the first time. The first attack involved drones and missiles, and due to prior warning there was sufficient time for interception. The second attack in October of that year relied mainly on ballistic missiles and was carried out without warning, reaching its targets within minutes. Satellite images showed that more than 30 missiles struck an airbase in southern Israel, suggesting either that Israel chose not to intercept those particular attacks or that its defense systems failed.
Analysts warn that future attacks could be larger and harder to intercept, especially if the Iranian regime makes greater use of more advanced weapons such as the “Fattah-1” and “Kheibar Shekan” missiles.
What Would Be the Consequences of the Iranian Regime Acquiring a Nuclear Weapon?
Many foreign policy experts warn that a nuclear-armed Iranian regime would pose a serious threat to the region. Some regional analysts fear that a nuclear-capable regime would likely become more emboldened and pursue a more aggressive foreign policy, not only regionally but also through expanding military and economic cooperation with China and Russia. The Iranian regime has supplied Moscow with various weapons systems, including drones and short-range ballistic missiles, to bolster Russian forces in the war in Ukraine.
There is also concern that the Iranian regime’s acquisition of a nuclear weapon could encourage other countries in the region to pursue similar capabilities, potentially triggering a dangerous nuclear arms race.
Although it remains unclear how the talks in Oman will ultimately proceed, it is evident that a difficult path lies ahead.
According to many nuclear experts, the Iranian regime will strongly oppose any complete dismantlement of its nuclear facilities, particularly as the nuclear program is now considered one of Tehran’s last remaining geopolitical levers after the weakening of many of its regional proxy forces.
