Can US President Trump attack on Iran's nuclear facilities to stop Iran from getting a Nuclear bomb ?

I wouldn’t rule anything out when it comes to Trump. However, if we examine history, consider the U.S. stance on North Korea. For years, America warned that North Korea couldn’t possess nukes or face invasion. It was a Red Line. But once NK acquired them, the U.S. could only maintain sanctions. They were unable to take action. We see a similar pattern with Iran. Although, Iran is in a better position than North Korea was. Despite sanctions, their economy continues to grow. With BRICS in play, sanctions are becoming weaker. Moving forward, BRICS nations are preparing to declare U.S. sanctions invalid among member state. This includes Iran, a member state of BRICS. Your country too, Brazil!
