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.

Iran’s nuclear facilities would be “extremely” difficult for Israeli forces to strike, defense sources have told The Post, adding that the Jewish state is willing to take such a bold step if officials deem it necessary — since President-elect Donald Trump has not objected to the possibility.
