Q: Verify if the sentiment of the following document towards the entity Kim Jong Un is Negative . 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.”

Q: Verify if the sentiment of the following document towards the entity Kevin Cramer is Neutral . North Dakota Rep. Kevin Cramer  has reversed course and will challenge Democratic Sen. Heidi Heitkamp  finally giving Republicans a top recruit in a state that President Trump won by more than 30 points and making it a prime pickup opportunity for the GOP in 2018.
On Facebook   Cramer  posted  he  will be announcing  his  Senate candidacy on Friday in Bismarck.
 Cramer  had initially said last month  he  wouldn't be challenging Heitkamp  leaving Republicans without a top-tier candidate against what should be one of Democrats' most vulnerable incumbents this year  serving in a consistently red state. The White House even reached out to  Cramer  to woo  him  to jump into the contest  but initially  he  elected instead to remain in  his  safe House seat.
But in recent days  he  began to waver on that initial decision. "There's certainly a growing snowball of encouragement coming out of the state  " Cramer  told reporters at the Capitol on Tuesday  according to CNN.
Former state party chairman Gary Emineth announced earlier this week he was dropping out of the Senate primary  in anticipation that  Cramer  was going to run. The Atlantic also reported that if  Cramer  did run for Senate  state Sen. Tom Campbell  the other major candidate in the race  was likely to run for  Cramer 's open House seat instead  clearing the primary field for the congressman.
 His  change of heart is a bright spot for Senate Republicans who have struggled to find top recruits in other states as well  despite being blessed with a very favorable 2018 map where 10 Democrats are up for re-election in states that Trump won. Republicans hold just a narrow 51-49 Senate majority  and they have two vulnerable seats they're defending in Nevada and Arizona.

IBM  whose full name is International Business Machines Corp  accounted for most of the stock sales that  Buffett  and  his  deputies Todd Combs and Ted Weschler made in the quarter.
In May   Buffett  revealed  he  had begun selling IBM  telling CNBC  he  did not value Big Blue as highly as  he  did six years earlier when  he  started buying.
âIBM is a big strong company  but theyâve got big strong competitors  too â  he  said.
The IBM investment had been viewed as a surprise  given the 87-year-old Buffettâs resistance to investing in technology companies and businesses  he  found harder to understand.
