After recently suggesting that Secretary of State Rex Tillerson was “wasting his time” talking directly to North Korean officials, 45 tweeted a similar sentiment, but added a very disturbing alternative.

“Presidents and their administrations have been talking to North Korea for 25 years, agreements made and massive amounts of money paid,” the president tweeted. “hasn't worked, agreements violated before the ink was dry, makings fools of U.S. negotiators. Sorry, but only one thing will work!”

So… that “one thing” is what exactly? War? When asked by reporters later in the day, Trump would only say, "You'll figure that out pretty soon."

White House press secretary Sarah Huckabee Sanders was reached by CNN and confirmed that all options on still on the table.

Social media also reacted to the tweets. See what Twitter had to say below.
