President Donald Trump said Saturday that diplomacy with Iran is now “much easier” following US and Israeli strikes that killed Supreme Leader Ali Khamenei.

Speaking to CBS News in a phone interview, Trump said the military operation had weakened Iran’s position and could open the door to negotiations.

“Much easier now than it was a day ago, obviously,” he said when asked about the prospects for a diplomatic solution. “Because they are getting beat up badly.”

Trump also praised the operation’s outcome, calling Saturday’s strikes “a great day for this country, a great day for the world.”
