Associated Press Iran is withdrawing from the 2015 nuclear deal, a move that could be perceived as the country taking a big step toward obtaining a nuclear weapon. This announcement comes after President Donald Trump ordered a strike that killed Iran's top military leader, Maj. Gen. Qassem Soleimani. Trump withdrew the US from the 2015 nuclear deal in May 2018, and this moment is widely viewed as the catalyst for a series of escalatory events that have raised fears of a potential war.
