WASHINGTON, Feb. 5 (Xinhua) -- Days before the Winter Olympics kick off in South Korea, U.S. President Donald Trump is continuing to pressure the top leader of the Democratic People's Republic of Korea (DPRK), Kim Jong Un, to make him abandon his nuclear program.

Trump and Kim have in recent months been engaged in a war of words, with Kim claiming he has a nuclear device that could hit the United States. Trump has warned Kim that attacking the nation that is home to the world's most powerful military would be the worst mistake Pyongyang could make.

In his State of the Union address last week, Trump said he would exert "maximum pressure" on the DPRK, and emphasized what he said was its poor human rights record.

On Friday, the president continued on that theme, inviting a handful of defectors from the DPRK to the White House to underscore the issue.

Analysts say the emphasis on human rights is a new tactic to ratchet up pressure on Pyongyang.

Trump's hope is that highlighting what Washington says are Pyongyang's numerous human rights abuses will "maintain pressure on Pyongyang and not allow the regime to use the Olympics to 'normalize' itself" in front of the world, Troy Stangarone, senior director at the Korea Economic Institute, told Xinhua.

"However, this will be challenging (for Trump), since the overarching narrative that the Olympics has historically represented is one of hope and the future," Stangarone said.

For its part, Pyongyang says the United States is responsible for a number of human rights abuses, from racism to inequality to the use of marijuana.

The DPRK's Korean Central News Agency (KCNA) released its own report on what it called U.S. human rights abuses, shortly after Trump's State of the Union address.

The report noted what it said was the increasing use of marijuana in the United States, saying that "the number of marijuana users in the U.S. was more than 20 million, a 3 percent increase as compared with that of a decade ago."

The DPRK in the past blasted the United States for its poor human rights record, and wrote in a 2014 report that life in the United States is a "living hell."
