Exclusive-US intelligence indicates limited new damage to Iran's nuclear program, sources say

By Gram Slattery, Jonathan Landay and Erin BancoWASHINGTON, May 4 (Reuters) - 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.
