July 8 (UPI) -- U.S. President Donald Trump ended his time at the NATO summit in Ankara, Turkey, with a press conference Wednesday in which he praised other leaders at the summit, called it "a great meeting" and said, "there was a lot of love in that room, a lot of unity."

It was a marked change in tone. Earlier in the day, Trump had complained about NATO members' defense spending, especially that of Spain, and said he wants to cut off all trade with the country. He called the Spanish "hopeless, bad people," The New York Times reported.

He complained that NATO countries "didn't want to help us with the number one state sponsor of terror, that's Iran." He called Iran's leaders "scum" as the United States renewed attacks against Iran.

Trump also repeated Wednesday that he still wants to take Greenland from Denmark, remarks that led Danish Prime Minister Mette Frederiksen to say that her country would defend its territory.
