From The Guardian President Trump is hesitant to approve U.S. strikes on Iran unless it’s certain the Fordow nuclear facility can be destroyed using the GBU-57 “bunker buster” bomb. ➡️ While some defense officials believe the bomb could work, others argue only a tactical nuclear weapon could destroy the deeply buried site. ➡️ Trump has ruled out nuclear options and is holding off on strikes for now, hoping the threat alone might push Iran to negotiate. — The Guardian
