The Trump administration is set to begin negotiations with Iran in an effort to reach a new nuclear deal. The Iranians are looking for an updated version of the Obama-era agreement, while the Americans want a deal that goes further, including dismantling Iran's nuclear-fuel enrichment infrastructure and ending support for proxy forces. The negotiations come at a critical time, as Iran's nuclear program continues to advance and snapback sanctions are set to expire soon. The pressure is on for the Trump administration to secure a deal that is tougher on Iran than the previous one.
