FILE – In this Saturday, Feb. 11, 2017, file photo, U.S. President Donald Trump, right, listens to Japanese Prime Minister Shinzo Abe as they make statements about North Korea at Mar-a-Lago in Palm Beach, Fla. North Korea often marks significant dates by displaying military capability, and South Korean officials say there’s a chance the country will conduct its sixth nuclear test or its maiden test launch of an ICBM around the founding anniversary of its military on Tuesday, April 25. Trump spoke by phone with both the Japanese and Chinese leaders Monday, April 24. Abe and Trump agreed to urge North Korea to refrain from what Abe called provocative actions.
