Former NBA star Dennis Rodman said North Korean leader Kim Jong Un didn't really "understand" President Donald Trump until he gave him a copy of the president's book, "The Art of the Deal," for his birthday in 2017.
In a recent interview with TMZ, Rodman said, "I think [Kim] didn't realize who Donald Trump was at that time, I guess, until he started to read the book and started to get to understand him."
Rodman, who considers Kim a friend and has made a number of visits to North Korea, said he believes the North Korean leader has had "a change of heart" when it comes to both Trump and the American people. The former NBA player didn't take full credit for this, but still feels his efforts at basketball diplomacy with North Korea played a significant role in the recent warming of relations.
"I don't want to take all the credit. I don't want to sit there and say, 'I did this, I did that.' That's not my intention," Rodman said. "My intention was to go over and be a sports ambassador to North Korea so people understand how the people are in North Korea. I think that has resonated to this whole point now."
Trump is set to meet with Kim at some point in the near future to discuss North Korea's nuclear program, though a location and date have not yet been announced. Rodman is seemingly very pleased with this development.
"I'm not the president. I'm just one person. I'm just one person and I'm so happy that things are going well," Rodman said.
In 2017 North Korea conducted a series of long-range missile tests as part of its broader ambition to develop a nuclear weapon capable of reaching the mainland US. This led to a war of words between Trump and Kim as well as harsh economic sanctions to be leveled against Pyongyang by the international community.
But the tide has turned in 2018 as North and South Korea have rekindled relations. Kim recently traveled to South Korea for a historic summit with President Moon Jae-in, in which the two leaders vowed to denuclearize the Korean Peninsula and work toward formally ending the Korean War.
Moon, as well as a number of Republican lawmakers back in the US, have given Trump a great deal of credit for these developments and have suggested the president should win the Nobel Peace Prize for his efforts in pressuring North Korea.
