[EX Q]: Rhetoric between President Donald Trump and North Korean leader Kim Jong Un has escalated. In response  North Korea’s foreign minister reportedly said the nation may set off the “most powerful” hydrogen bomb detonation in the Pacific. No other details were provided  but at face value  such a blast would be 1 000 times as powerful as the Hiroshima bombing. Atmospheric testing of nuclear weapons can lead to multiple dangerous scenarios.
Ri Yong Ho  the foreign minister of the isolated nation  reportedly told journalists that North Korean leader Kim Jong Un is considering such a test blast.
“It could be the most powerful detonation of an H-bomb in the Pacific ” Yong Ho told reporters at the United Nations in New York on Thursday  according to a story by South Korea’s Yonhap News Agency. “We have no idea about what actions could be taken as it will be ordered by leader Kim Jong Un.”

The suggestion came in response to bellicose rhetoric exchanged between US President Donald Trump and  Jong Un .
In a speech before the United Nations General Assembly on Tuesday  Trump called  Jong Un  a suicidal “rocket man” and threatened to “totally destroy” North Korea if the US is “forced to defend itself or its allies.”  Jong Un  allegedly responded with a written statement  in which he called Trump a “mentally deranged US dotard” and said that “a frightened dog barks louder.”
“Trump is basically creating audience costs for  Kim  to back down ” Jeffrey Lewis  director of the East Asia Nonproliferation Program at the Middlebury Institute of International Studies at Monterey  told Vox. “If you dare  Kim   it creates pressure for  him  to respond with  his  own provocation.”
“The stakes and heat in this conflict have not been this high since the Korean War ” Tristan Webb  a senior analyst for NK News  said in a story published by the outlet on Friday. “Kim Jong Un said in July that the … showdown was entering its final phase. He appears psychologically prepared for conflict.”

[EX Q]: Cook County Sheriff Tom Dart  is going to court to unmask the person who alleged in emails to politicians  Chicago police investigators and journalists that  Dart  attacked  his  wife at their South Side home.
 Dart  filed the legal papers Wednesday in his personal capacity  not as sheriff  and hired lawyer John F. Winters Jr.  who specializes in defamation cases. Such court filings are often a prelude to a defamation lawsuit filed against the person behind anonymous emails or web postings.
“ Tom  has been subjected to sustained attacks on  his  integrity  and even threats to  his  life  during  his  tenure as sheriff ” said Dennis Culloton  who is acting as  Dart ’s personal spokesman  in a statement. “Over the past several months  these attacks have escalated to include false and vicious rumors involving his wife and family  perpetuated by cowards who hide behind fake email addresses and anonymous blogs. Through this filing we hope to hold those people accountable.”
The first of two October emails cited in the filing allege  Dart  “committed a Domestic Battery” on his wife “causing visible injuries to her face” that were observed by responding Chicago and Cook County sheriff’s police on either Oct. 11 or 12. They allege a police report was taken but that the attacker was listed as “unknown” and that a 911 call was placed to  Dart ’s home.
“This incident is being attempted to be swept under the rug ” the email’s author  who describes himself as a “Cook County taxpayer” named “Dan ” writes.  “Tom Dart  should not be able to get away with this!”
Records show a complaint was also made to a Chicago police oversight agency in October alleging that police refused to act or take reports “in regards to an incident that occurred at  Sheriff Tom Dart’s  home that involved  his  wife and  his  girlfriend.”
