He suggested that the rogue nation is more than an urgent problem.
"This is a threat of both rhetoric and growing capability, and we will be working with the international community to address this," Mattis said. "We are working through the United Nations, we are working our allies, and we are working diplomatically including with those who we might be able to enlist in this effort to get North Korea under control."
Back in 2012, Mattis viewed Iran as our main existential threat, but has pivoted to North Korea because its leader is a freaking lunatic and has even threatened the United States with nuclear missiles.
"Right now, it appears to be going in a very reckless manner in what its conduct is portraying for the future and it's got to be stopped," Mad Dog Mattis said.
In fact, it's likely North Korea is readying for another nuclear test while the left is concerned with recycling and genderless bathrooms.
Mattis was also asked about a U.S. general's comment regarding Russia supplying weapons to the Taliban. He said that he's seen activities between the two, but wouldn't confirm if weapons exchange actually took place.
When asked about Assad's future in Syria, he mostly deflected from the issue and claimed no decision has been made on deploying more U.S. troops to lovely Afghanistan saying "I have not made a recommendation to the president."
