A new U.S. intelligence report finds that Iran’s nuclear program has been set back only a few months after U.S. strikes, not totally destroyed as President Donald Trump has said.

Trump says the U.S. Iran strikes "obliterated" key nuclear sites, but an early intel assessment says Iran could reconstitute some of its capabilities in months, sources said.

Preliminary classified findings indicate that the attack sealed off the entrances to two facilities but did not collapse their underground buildings.
