Story highlights  Kim  raises possibility of North Korean athletes in Winter Olympics in South Korea
(CNN)  North Korean leader Kim Jong Un  has warned the United States that  his  country's nuclear capabilities are now complete and the nuclear launch button is always on  his  desk.
"The entire mainland of the US is within the range of our nuclear weapons and the nuclear button is always on the desk of my office. They should accurately be aware that this is not a threat but a reality " said  Kim  during  his  annual New Year's Day address  according to a CNN translation of the speech.
"No matter how much America wants to attack us with their military might and nuclear power  they know that now we possess such great nuclear power and therefore they will not dare "  Kim  said  adding that  his  country's greatest achievement of 2017 was the "historic accomplishment of completing our nuclear capabilities."
Since coming to power   Kim  has overseen a dramatic increase in the pace of North Korea's missile program. As of February last year  Pyongyang has fired off 23 missiles  improving its technology with each launch. In September  the regime carried out its sixth and most powerful nuclear test.
Euan Graham  director of the International Security Program at the Lowy Institute  told CNN that  Kim 's nuclear button comment is "effectively just noise."

Conservative commentator and author Laura Ingraham claimed in her book released Tuesday that someone at the 2016 GOP convention suggested that she move to Texas to primary Sen. Ted Cruz -LRB- R-TX -RRB- in 2018 . 
"People were so torched by Cruz 's failure to endorse Trump that talk of primarying him ignited almost the moment he walked off the stage ," Ingraham wrote in her new book , Billionaire at the Barricades : The Populist Revolution from Reagan to Trump . 
Cruz eventually endorsed Trump on September 23 , four months after he dropped out of the presidential race and resumed his work in the U.S. Senate . 
Ingraham witnessed the moment Cruz declined to endorse President Trump in his speech at the 2016 Republican National Convention in Cleveland , Ohio . 
Moments before he took the stage , Ingraham said she told Cruz to "endorse" Trump in his speech . 
Instead of endorsing Trump , Cruz told Americans to "vote your conscience" in his convention speech , causing the crowd to react with jeers and boos . 
In her book , Ingraham recounted how GOP-mega donor Sheldon Adelson told security not to let Cruz into his suite following the speech .
