Billionaire investor George Soros on Thursday warned that President Donald Trump's administration threatens to put the U.S. and North Korea on a war footing. He described the administration as "a danger to the world" but said he expected a landslide win during the 2018 midterm elections in the U.S. to turn the tide on the presidency. The 87-year-old Hungarian-born investor's comments came during a speech in Davos, Switzerland at the World Economic Form. Soros in the past has expressed concerns about Trump and democracy across the globe since Britain voted to exit from the European Union in June of 2016. According to The Wall Street Journal, Soros lost about $1 billion on wrong-way bets following the stock market's rally after Trump's election victory. Soros helped pioneer the hedge-fund industry and is best known for an outsize bet against the pound USDGBP, -0.27% in the early 1990s.
