WASHINGTON, Jan. 2 (Yonhap) -- U.S. Defense Secretary Mark Esper on Thursday urged Kim Jong-un to exercise "restraint" after the North Korean leader threatened to reveal a "new strategic weapon."
Kim made the remark in a New Year's message that expressed his frustration over stalled denuclearization talks with the U.S.
Experts have said the "strategic weapon" Kim said the world will see in the near future could be an intercontinental ballistic missile.
"We would urge restraint by Kim Jong-un," Esper said in an interview with Fox News, noting that the best path forward is still a political agreement on denuclearizing North Korea.
"We are on that path. We want to remain on that path, and we would obviously urge Kim Jong-un and his leadership team to sit back down at the negotiation table to do that," he said.
Esper made clear, however, that the U.S. military stands ready to "fight tonight" if necessary.
"We have a full array of forces. They are ready. They're Air and Naval, Marine, Army forces. We have our South Korean partners with us, and then we have a broader set of allies and partners out there as well," he said. "So I'm confident in the readiness of our forces to deter North Korean bad behavior and should that fail, to fight and win as necessary."
Questions have been raised about the readiness of South Korean and U.S. forces in the wake of the allies' decision to scale back some joint military exercises in support of the diplomatic process.
North Korea denounces the drills as rehearsals for an invasion of the regime, and in his New Year's message, Kim complained that the allies continue to conduct their exercises despite what he said was a personal promise from U.S. President Donald Trump to stop them.
Kim added that under such conditions he sees no reason to be bound by his self-declared moratorium on nuclear and ICBM tests.
Trump and Kim have had three meetings to try to reach a deal on dismantling North Korea's nuclear weapons program in exchange for U.S. sanctions relief and security guarantees.
But negotiations between the sides have faltered since the leaders' second summit in Vietnam in February due to wide gaps over how to match their steps.
Trump said Tuesday following Kim's remarks that he still believes the North Korean leader will stick to his commitment to denuclearize.
"I think he's a man of his word," he said.
The same day, U.S. Secretary of State Mike Pompeo told Fox News that the U.S. hopes Kim will "take a different course."
"We're hopeful that Chairman Kim will make the right decision, (that) he'll choose peace and prosperity over conflict and war," he said.
