[Q]: Liberal billionaire  George Soros  told global leaders and economists at Davos Thursday night that President Trump is a "danger to the world " who has helped bring the planet to the brink of nuclear war.
 Soros  the 87-year-old Hungarian-born financier   spoke at the World Economic Forum  harshly criticizing Trump  who was not present.  He  said the threat of nuclear war has grown as the U.S. and North Korea continue to antagonize each other.
"The situation has deteriorated " said  Soros . "Not only the survival of open society  but the survival of our entire civilization is at stake."
" ... the survival of our entire civilization is at stake." - George Soros
 Soros   whose dire predictions a year ago that President Trump would crash the U.S. economy have proven wildly wrong  also forecast a Democratic landslide in the 2018 midterm elections would push back the danger of the Trump administration. He said his Open Society Foundation is funding more institutions in the U.S. rather than the third world to ensure a Democratic victory in November.
 Soros  also referred to social media giants like Facebook and Google as a âmenaceâ to society. Soros likened the businesses to gambling companies that âdeliberately engineer addiction to the services they provide.â
During last yearâs conference in Davos   Soros  predicted negative prospects for the stock market under Trump. Since then  the S&Pâs 500 Index rallied almost 30 percent  according to Bloomberg.

[Q]: While Klay Thompson closed the game with the final seven points to give Golden State the victory  the head-to-head battle between Durant and LeBron James  the best players in the sport  will be analyzed and dissected most.
Twice in the final two minutes   James  tried to drive past Durant. Both times   James  lost the ball out of bounds  resulting in Cleveland turnovers that essentially iced the game for Golden State.
Replays left the impression that both plays could have been called fouls  though  James  only took issue with the second one â when Durant blocked a shot off Jamesâs hands and out of bounds  giving the ball back to the Warriors after a replay review with 24.5 seconds left. Durantâs play prevented Cleveland from getting a shot at tying the score.
âI lost it on the left wing â  James  said. â He  got me a little bit  but I lost that one. But obviously the overturned one   he  fouled me twice. But whatever. What are you going to do about it?â
Durant  not surprisingly  saw it a bit differently â particularly the debate about whether he fouled  James  that was ongoing on social media in the moments after the plays.
