President Donald Trump spoke to Sean Hannity about his landmark Singapore summit with North Korean dictator Kim Jong Un.

Trump said that as much as he "hated" to use violent rhetoric against Kim several months ago, "without the rhetoric, we wouldn't be here."

Trump said that after exchanging verbal barbs -- with Trump calling Kim "little rocket man" and Kim calling Trump "a dotard" -- the two men grew to further respect each other.

"We got a lot more done [Tuesday] than I ever thought possible," he said of the meeting with Kim.

Trump said he believes that Kim will "immediately" begin dismantling his nuclear complexes when he arrives back in Pyongyang.

He added that he and Kim discussed how relations were much different between previous American presidents and Kim's ancestors Kim Jong Il and Kim Il Sung.

Hannity also asked if there is a "history lesson" where it pertains to the initial rhetoric.

He said that President Ronald Reagan famously called the U.S.S.R. the "evil empire" before coming to an agreement to dismantle Checkpoint Charlie and tear down the Berlin Wall.
