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, according to three sources familiar with the matter, Reuters reported. 

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

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