Although President Trump has repeatedly stated that going to war with North Korea is not his preferred option, his statements on Sunday would seem to indicate that it’s the only outcome he’s now open to pursuing.

Donald Trump once again took to the social media platform Twitter to convey his foreign policy stance, claiming that American Secretary of State, Rex Tillerson, was wasting his time by pursuing talks with Kim Jong un’s despotic regime.

“I told Rex Tillerson, our wonderful Secretary of State, that he is wasting his time trying to negotiate with Little Rocket Man…” the President wrote on Twitter, adding, “…Save your energy Rex, we’ll do what has to be done!”

A few hours later, the president returned to the subject on Twitter, calling out past presidents for their failure to curb North Korea’s pursuit of nuclear weapons, and claiming that he won’t follow in their footsteps.

“Being nice to Rocket Man hasn’t worked in 25 years, why would it work now? Clinton failed, Bush failed, and Obama failed. I won’t fail.” He wrote.

Running in contrast to the President’s statements, Rex Tillerson was in Beijing this weekend, where he addressed his ongoing efforts to bring peace to the Korean peninsula through talks, as he and other prominent officials in Trump’s administration have continued to claim that the United States seeks a de-escalation of tensions that can only be brought about by North Korea’s leader, Kim Jong un, surrendering his nuclear arsenal and ceasing his pursuit of further weapons of mass destruction.

“We’ve made it clear that we hope to resolve this through talks,” Tillerson said.

“I think the most immediate action that we need is to calm things down,” he continued. “They’re a little overheated right now, and I think we need to calm them down first.”  When asked about the president’s statements, he again used the term “overheated” to describe them.
