Responding to reports that North Korea may have conducted an underground nuclear test, President Donald Trump lashed out on Twitter Sunday morning to say "appeasement" will not work with the "rogue nation."

As usual, the undiplomatic president first ran to Twitter to make his feelings known, writing, "North Korea has conducted a major Nuclear Test. Their words and actions continue to be very hostile and dangerous to the United States ... North Korea is a rogue nation which has become a great threat and embarrassment to China, which is trying to help but with little success."

He then made a vague war threat by writing, "South Korea is finding, as I have told them, that their talk of appeasement with North Korea will not work, they only understand one thing!"
