SEOUL, South Korea — North and South Korea reached an agreement Wednesday for their athletes to march together under one flag at the opening ceremony of the Winter Olympics next month, a powerful gesture of reconciliation that further complicates President Trump’s strategy for dealing with the nuclear-armed regime of Kim Jong-un.
South Korea, the host of the games, said it hoped a partnership in sports could contribute to a political thaw after years of high tensions on the Korean Peninsula. It came even as the prospect of war over the North’s nuclear and ballistic missile tests has loomed large.
