U.S. President Donald Trump plans to resume talks with Iran in Rome, but negotiators are not expecting a swift breakthrough in the decades-long dispute over Iran's nuclear program. Trump's administration is considering an interim deal ahead of a more detailed agreement. Trump has threatened to bomb Iran's nuclear sites if a deal cannot be reached, potentially leading the U.S. into a new conflict in the Middle East. Leading the U.S. negotiating team is Steve Witkoff, a Trump friend and real estate investor with no prior diplomatic experience. Witkoff's direct line to Trump is seen as a negotiating asset, but it remains to be seen if it will help secure a deal with Iran.
