Biden has vowed not to let Iran develop a nuclear weapon on his watch, but it remains unclear what steps Iran would have to take in order for the Biden administration to respond with direct hits, given that Tehran has already been reported to have stockpiled near-weapons-grade uranium and to be bolstering its weaponization capabilities.

White House national security adviser Jake Sullivan presented President Biden with options for a potential U.S. attack on Iran's nuclear facilities if the Iranians move towards a nuclear weapon before Jan.

Joe Biden reportedly discussed plans to strike Iran’s nuclear sites in the event Tehran moved closer to building a nuclear bomb before Donald Trump’s inauguration on Jan 20.
