Assessments suggest the timeline for Iran to build a nuclear weapon has not changed since last summer.
US intelligence assessments indicate that the time Iran would need to build a nuclear weapon has not changed since last summer, when analysts estimated that a US-Israeli attack had pushed back the timeline to up to a year.
This assessment remains unchanged even after two months of war launched by US President
Donald Trump, in part to prevent Iran from developing a nuclear bomb.The latest US and Israeli attacks, which began on February 28, have focused on conventional military targets, but Israel has hit several significant nuclear facilities.
Despite this, the unchanged timeline suggests that significantly impeding Tehran's nuclear program may require destroying or removing Iran's remaining stockpile of highly enriched uranium (HEU).The war has stalled since the US and Iran agreed to a truce on April 7 to pursue peace.
Tensions remain high as both sides appear deeply divided, and as Iran has choked traffic through the Strait of Hormuz, blocking some 20 percent of global oil supplies and igniting an energy crisis.US Secretary of Defense Pete Hegseth has stated that the US aims to ensure Iran does not obtain a nuclear weapon via ongoing negotiations with Tehran.
Prior to June's 12-day war, US intelligence agencies had concluded that Iran could produce enough bomb-grade uranium for a weapon within three to six months.
Following the June strikes on the Natanz, Fordow, and Isfahan nuclear complexes, this timeline was pushed back to about nine months to a year.The attacks destroyed or badly damaged the three enrichment plants known to be operating at the time.
However, the UN nuclear watchdog has been unable to verify the whereabouts of some 440 kilograms of uranium enriched to 60 percent, believing that about half is stored in an underground tunnel complex at the Isfahan Nuclear Research Center.
The International Atomic Energy Agency assesses the total HEU stockpile would be enough for 10 bombs if further enriched.US officials, including President Trump, repeatedly emphasize the need to eliminate Iran's nuclear program as a key objective of the war.
While Israel has struck nuclear-related targets, US attacks have focused on conventional military capabilities and Iran's leadership and military-industrial base.The unchanged estimates may stem from a lack of major nuclear targets that can be readily and safely destroyed following June's military action.
Some analysts argue that Iran still possesses all its nuclear material, which is likely located in deeply buried underground sites where US munitions cannot penetrate.
