WASHINGTON (AP) — President Donald Trump is betting that a beleaguered Iran is so vulnerable following a tumultuous 18 months in the Middle East that it might finally be ready to abandon its nuclear program. The renewed push to solve one of the most delicate foreign policy issues facing the White House and the Mideast will begin in earnest Saturday. That’s when Trump’s Middle East envoy, Steve Witkoff, and Iranian Foreign Minister Abbas Araghchi gather in the Middle East sultanate of Oman. Trump says he prefers a diplomatic solution, even as he warns Iran it will face “great danger” if talks don’t go well. He says, “They can’t have a nuclear weapon.”
