Input: Consider Input: 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."

Input: Consider Input: Earlier in the day  the company appeared to side with its chairman in dismissing the Journalâs article  saying in a statement that the newspaper account âreflected allegationsâ made by his ex-wife  Elaine Wynn  in her litigation against him and the company.
âThe idea that I ever assaulted any woman is preposterous â he said. âThe instigation of these accusations is the continued work of my ex-wife  Elaine Wynn  with whom I am involved in a terrible and nasty lawsuit in which she is seeking a revised divorce settlement.â
 A spokeswoman for Elaine Wynn  75   declined comment  but  her  Washington-based attorney  James Cole  told Reuters the notion that his client fomented the allegations in the Journal article âis just not true.â
The couple first married in 1963 and divorced in 1986. They remarried in 1991 and divorced again in 2010  according to court papers. In an escalating battle that followed their bitter second split  Elaine Wynn sued her former spouse in 2016 seeking to gain control over her 9.4 percent stock in Wynn Resorts.
