U.S. President Donald Trump doubled down Tuesday in the United States' standoff with nuclear-armed North Korea, reiterating that "all options" — an allusion to military action — remain on the table after Pyongyang launched a midrange missile over its close Asian ally Japan.

"Threatening and destabilizing actions only increase the North Korean regime's isolation in the region and among all nations of the world," Trump said in a statement. "All options are on the table."

The U.S. leader made the remarks after the North test-fired a ballistic missile over Hokkaido early on Tuesday morning, the first unannounced launch of a missile designed to carry a nuclear payload to fly over Japan.
