WASHINGTON – U.S. 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 U.S.-Israeli attack had pushed back the timeline to up to a year, according to three sources familiar with the matter.

The assessments of Tehran’s nuclear program remain broadly unchanged even after two months of a war that U.S. President Donald Trump launched in part to stop the Islamic Republic from developing a nuclear ​bomb.

The latest U.S. and Israeli attacks that began on Feb. 28 have focused on conventional military targets, but Israel has hit a number of significant nuclear facilities.
