How close is Iran to a nuclear bomb?

Iran’s nuclear breakout time has become a key question as President Trump considers whether to bomb the Islamic regime’s key underground nuclear facility. 

Israeli Prime Minister Benjamin Netanyahu, in justifying his unprecedented strikes on the regional rival last week, said Iran was “marching very quickly” toward a nuclear weapon. 

That seemed to diverge from U.S. assessments — voiced by Director of National Security Tulsi Gabbard in a March congressional hearing — that Iran was not actively building a nuclear weapon.
