(CNN) -- If any American has the power of persuasion over North Korea's defiant young ruler, it might be eccentric ex-basketball star Dennis Rodman.
So when Rodman digitally called for Kim Jong Un to release U.S. citizen Kenneth Bae, he may have a shot at a response.
"I'm calling on the Supreme Leader of North Korea or as I call him "Kim", to do me a solid and cut Kenneth Bae loose," Rodman tweeted.

Bae was sentenced to 15 years of hard labor last month after he was convicted of unspecified "hostile acts" against North Korea. The country's state-run Korean Central News Agency said the Korean-American was arrested November 3 after arriving as a tourist in Rason City, a northeastern port near the Chinese border.

A North Korean court has sentenced Kenneth Bae, a U.S. citizen, to 15 years of hard labor for committing "hostile acts" against the state. Those alleged acts were not detailed by the country's state-run news agency when it announced the sentence Thursday, May 2. Bae, here in a photo from a Facebook page titled Remember Ken Bae, was arrested in November. "This was somebody who was a tour operator, who has been there in the past and has a visa to go to the North," a senior U.S. official told CNN.
North Korea has arrested Americans before, only to release them after a visit by a prominent dignitary. Journalists Laura Ling, center, and Euna Lee, to her right, spent 140 days in captivity after being charged with illegal entry to conduct a smear campaign. They were freed in 2009 after a trip by former President Bill Clinton.
Former President Jimmy Carter negotiated the release of Aijalon Gomes, who was detained in 2010 after crossing into North Korea illegally from China. Analysts say high-level visits give Pyongyang a propaganda boost and a way to save face when it releases a prisoner.
Eddie Yong Su Jun was released by North Korea a month after he was detained in April 2011. His alleged crime was not provided to the media. The American delegation that secured his freedom included Robert King, the U.S. special envoy for North Korean human rights issues.
Robert Park was released by North Korea in 2010 without any apparent U.S. intervention. The Christian missionary crossed into North Korea from China, carrying a letter asking Kim Jong Il to free political prisoners and resign. North Korea's state-run news agency said Park was released after an "admission and sincere repentance of his wrongdoings." Here, Park holds a photo of Kim and a malnourished child during a protest in Seoul.
Josh Fattal, center, Shane Bauer and Sarah Shourd were detained by Iran while hiking near the Iraq-Iran border in July 2009. Iran charged them with illegal entry and espionage. Shourd was released on bail for medical reasons in September 2010; she never returned to face her charges. Bauer and Fattal were convicted in August 2011, but the next month they were released on bail and had their sentences commuted.
An Iranian court threw out a death penalty conviction last year for Amir Hekmati, a former U.S. Marine charged with spying. But he still remains in solitary confinement at Iran's notorious Evin Prison. Hekmati was detained in August 2011 during a visit to see his grandmother; his family and the Obama administration deny accusations that he was spying for the CIA.
Haleh Esfandiari, an Iranian-American scholar, was also detained at Evin Prison, spending months in solitary confinement before Iran released her on bail in August 2007. Esfandiari was visiting her ailing mother in Tehran when she was arrested and charged with harming Iran's national security.
Alan Gross, at right with Rabbi Arthur Schneier, has been in Cuban custody since December 2009, when he was jailed while working as a subcontractor. Cuban authorities say Gross tried to set up illegal Internet connections on the island. Gross says he was just trying to help connect the Jewish community to the Internet. Former President Jimmy Carter and New Mexico Gov. Bill Richardson have both traveled to Cuba on Gross' behalf, but they were unable to secure his release.
Sixteen Americans were among the dozens arrested in December 2011 when Egypt raided the offices of 10 nongovernmental organizations that it said received illegal foreign financing and were operating without a public license. Many of the employees posted bail and left the country after a travel ban was lifted a few months later. Robert Becker, right, chose to stay and stand trial.

Rodman: I'm going back to North Korea
Bae's sister, Terri Chung, told CNN's Anderson Cooper last week that her brother is not a spy.
"He has never had any evil intentions against North Korea, or any other country for that matter," Chung said.
She said her brother owns a tour company and was in North Korea for work.
"He didn't have any problems going there last time, last year five times, so he didn't have any reason to suspect that there would be any trouble this time around," she said.
U.S. officials have struggled to establish how exactly Bae fell afoul of North Korean authorities. The North Korean statement on his conviction provided no details of the allegations against him.
"This was somebody who was a tour operator, who has been there in the past and has a visa to go to the North," a senior U.S. official told CNN on Monday, speaking on condition of anonymity because of the diplomatic sensitivity of the issue.
But NK News, a U.S.-based website that focuses on North Korea, suggests Bae has served as a missionary trying to convert North Koreans.
"I knew that Jesus wanted me to be a 'channel' to the North," Bae told a Korean congregation at a St. Louis church in 2011, NK News reported. "This year, I'm working at taking several short term missionary teams into North Korea."
Bae's sentencing came after weeks of intense rhetoric from North Korea, which conducted its third nuclear test in February and launched a satellite into orbit atop a long-range rocket in December.
Washington responded by deploying additional missile interceptors on the West Coast, dispatching a missile defense system to the Pacific territory of Guam and bolstering annual U.S.-South Korean military exercises with overflights by nuclear-capable B-2 and B-52 bombers.
Rodman, the heavily pierced NBA Hall of Famer, made headlines when he befriended North Korea's supreme leader during a visit in February.
"You have a friend for life," Rodman told Kim after the two men sat next to each other watching an unusual basketball exhibition in Pyongyang.
But Rodman said he is not an official diplomat between the United States and North Korea.
"I'm not a politician," he tweeted. "Kim Jung Un & North Korean people are basketball fans. I love everyone. Period. End of story."
