TOKYO — North Korean leader Kim Jong Un said Monday the United States should be aware that his country’s nuclear forces are now a reality, not a threat. But he also struck a conciliatory tone in his New Year’s address, wishing success for the Winter Olympics set to begin in the South in February and suggesting the North may send a delegation to participate.
