President Trump said that he wants to remove Iran's leadership, and has a list of people who "would do a good job" as a leader.

"We want to go in and clean out everything," Trump told NBC News on Thursday. "We don't want someone who would rebuild over a 10-year period. We want them to have a good leader. We have some people who I think would do a good job,” he added, declining to name anyone.

Trump said that he is taking steps to ensure that the people on his list make it through the war alive.

"We are watching them, yeah," he said.

The president's comments come after Iranian Supreme Leader Ayatollah Ali Khamenei was killed over the weekend during U.S. and Israeli strikes on Iran.

Trump also responded to Iranian Foreign Minister Abbas Araghchi’s telling “NBC Nightly News” that his country is ready for a ground invasion by U.S. and Israeli forces.

The president called it a "wasted comment" and suggested an invasion is not something he is thinking about at this time.

“It’s a waste of time. They’ve lost everything. They’ve lost their navy. They’ve lost everything they can lose,” Trump said, adding that the pace and intensity of strikes will continue.
