Trump's Iran deal decision: What happens now
President Trump announced today that he will withdraw the U.S. from the 2015 deal under which Iran scaled back its nuclear program in exchange for sanctions relief.
Why it matters: This is likely to be one of the most consequential decisions of Trump's presidency. It could see Iran ramp up its nuclear program, and raises the likelihood of military confrontation. It will also have big economic consequences for Iran and for the global oil trade, and ramifications for U.S. relationships with key European allies.
