According to online reports, according to the AXIOS website, Trump advisers revealed that a key question that has lingered on Trump's mind recently is: If the United States joins Israel's war and throws giant earth-penetrating bombs, can it truly destroy Iran's most heavily guarded nuclear facilities? Trump's doubts on Wednesday about the success of the operation was one reason why he was still weighing whether to launch a strike. US officials said Trump needs to confirm three points-that such strikes are necessary, that they will not drag the United States into a protracted war in the Middle East, and the most important thing is that they can truly achieve the goal of destroying Iran's nuclear program. If Trump decides to go to war, he will almost certainly destroy the Fordo nuclear facility. According to US officials, Trump specifically consulted with military advisers whether the giant earth-penetrating bomb could destroy Fordo. Although Pentagon officials expressed confidence, Trump did not seem fully convinced. Current and former officials pointed out that although the bomb has been tested many times, it has never been used in combat. (Jin Shi)
