Trump defends Iran war as U.S. steps up sanctions

President Trump says he has no regrets about starting the Iran war and would do it again, arguing Iran could have used a nuclear weapon; as markets brace for a longer conflict, the White House is intensifying economic pressure with planned sanctions on a large bank and actions against Iranian-linked banks, including Dubai branches of an Egyptian bank and a major Turkish bank, while Trump predicts a settlement after the elections and denies reports of damage to U.S. assets.
