âWe have destroyed the enemyâs risk-taking provocations at every move â  Kim Jong Un  said in a speech.  He  did not mention the United States  which North Korea considers its main enemy and regularly threatens to destroy in a sea of flames.
âBy sending key figures like his sister  Kim Jong Un is aiming to send a signal to the South that it is giving more weight to inter-Korean ties while driving a wedge between South Korea and the United States â said Kim Sung-han  a former South Korean vice foreign minister.

Example Input: SAN FRANCISCO â Sayfullo Saipov  the 29-year-old suspect in Tuesday's deadly New York truck attack  earned money the way many gig economy works do. He drove for Uber.
But the fact that  Saipov  raised no flags for the ride-hailing company when it conducted its standard background check shows just how difficult it is to screen for potentially criminal behavior if there is no track record.
 Saipov  drove more than 1 400 trips for Uber in the past six months. Authorities continue to investigate the suspect  who came from Uzbekistan in 2010 and settled in Paterson  N.J. To date  his biggest offense seems to be from 2015  when he was cited by police for towing a trailer that was too long.
This undated photo provided by St. Charles County Department of Corrections via KMOV shows the Sayfullo Saipov.

The company's response to that incident was the same as its statement after  Saipov  rammed  his  rented truck into bicyclists  killing 8. An Uber representative said the company was "horrified" at the senseless act of violence as was cooperating with federal officials.
Uber said  Saipov  had been banned from the Uber app.

Example Input: NEW YORK (Reuters) - Warren Buffett  chairman and CEO of Berkshire Hathaway Inc (BRKa.N)  said his conglomerate  which is sitting on $116 billion of cash  is âmore inclinedâ to repurchase stock than pay dividends as a means to use excess cash.
Speaking on CNBC television on Monday   Buffett  said the corporate income tax rate cut signed into law by U.S. President Donald Trump in December is a âhuge tailwindâ for U.S. companies and that it is âreally good for Berkshire.â
In his annual letter to Berkshire shareholders on Saturday   Buffett  lamented his inability to find big companies to buy and said his goal is to make âone or more huge acquisitionsâ of non-insurance businesses to bolster results at Berkshire.
 Buffett  said finding things to buy at a âsensible purchase priceâ has become a challenge and is a major reason Berkshire is awash with $116 billion of low-yielding cash and government bonds  whose average maturity was 88 days as of the end of 2017.
âI am fairly confident we will find ways to deployâ Berkshireâs excess cash   Buffett  said on CNBC. âThe best chance to deploy money is when things are going down.â
 Buffett  says  he  has confidence in Wells Fargo & Co (WFC.N) Chief Executive Tim Sloan  as  he  tried to move the third-largest U.S. bank past scandals over how it treated customers including by creating unauthorized accounts.
 Buffett  likened the situation to when  he  was installed in 1991 as chairman of Salomon Brothers Inc after a former chief executive failed to tell regulators that a trader was submitting fake bids at Treasury auctions.
âDigging your way out of it takes time â  Buffett  said. â He âs got a lot to clean up.â
 Buffett  raised red flags about ordinary investors using borrowed cash to buy stocks  or buying âon margin.â
 Buffett  said it was âcrazyâ to borrow money to buy stocks and that âit is insane to risk something you have and needâ for the sake of leveraging up on stocks.  Buffett  said investors might get a âeuphoric surgeâ if they double their money in stocks  but would not be âhappier.â
