During an interview with CNN on Nov. 28, Republican Sen. Lindsey Graham of South Carolina warned that the U.S. will go to war with North Korea "if things don't change."
Graham's warning came after North Korea tested a new missile which it claims can reach the U.S. East Coast.
"If we have to go to war to stop this, we will," Graham told CNN. "If there's a war with North Korea it will be because North Korea brought it on itself, and we're headed to a war if things don't change."
Earlier that day, North Korean state media announced the new missile, the Hwasong-15, reached an altitude of 2,780 miles and flew 590 miles, according to Reuters. State media also claimed the missile is capable of re-entering the atmosphere.
"After watching the successful launch of the new type ICBM Hwasong-15, [North Korean leader] Kim Jong Un declared with pride that now we have finally realized the great historic cause of completing the state nuclear force, the cause of building a rocket power," state media declared, according to Reuters.
U.S. Secretary of Defense James Mattis confirmed the North Korean claims, saying the new missile went "higher, frankly, than any previous shot they have taken," according to CNN.
North Korea is now capable of striking "everywhere in the world basically," he added.
"We will take care of it," President Donald Trump said, reports CNN. He did not specify what actions would be taken.
During his appearance on CNN, Graham stated neither he nor Trump wants to go to war.
"But we're not going to let this crazy man in North Korea have the capability to hit the homeland," he said.
"[Trump] is ready, if necessary, to destroy this regime to protect America, and I hope the regime understands that if President Trump has to pick between destroying the North Korean regime and the American homeland, he's going to destroy the regime," Graham continued. "I hope China understands that also."
On Nov. 29, Trump tweeted that he had spoken to Chinese President Xi Jinping about North Korea's latest provocation. China is North Korea's only ally.
"Just spoke to President XI JINPING of China concerning the provocative actions of North Korea. Additional major sanctions will be imposed on North Korea today. This situation will be handled," Trump tweeted.
The missile test comes about a week after Trump put North Korea back on the list of state sponsors of terrorism. The country was previously removed from the list in 2008 by President George W. Bush during a denuclearization negotiation, according to NPR.
North Korea called its return to the list a "serious provocation and violent infringement," according to Reuters.
