DAVID MUIR: We begin tonight with the breaking news, after the major U.S. strikes on Iran, tonight here, the new classified intelligence report, a preliminary report on what could be a reality check now on the U.S. attack on Iranian nuclear enrichment facilities. President Trump had declared they were completely and totally obliterated, but tonight, sources say this new preliminary Pentagon report finds the damage was limited, saying Iran's nuclear program was only set back a few months. That daring military mission, B-2 bombers setting off from Missouri, deploying 30,000 bunker buster bombs for the first time on the battlefield- 30,000-pound. Satellite imagery showing the target sites, signs of damage, holes in the ground, but it remains unclear just how much and what kind of damage they did below. Sources say the preliminary report also indicates much of Iran's stockpile of enriched uranium was not destroyed, because it was likely moved before the U.S. attack
