North Korea, which unleashed another round of scathing rhetoric accusing the United States of pushing the region to the "brink of war," could be planning a missile launch soon, a U.S. official said Thursday.
Communications intercepts in recent days indicated that Pyongyang could be planning to launch a mobile ballistic missile in the coming days or weeks, the official first told CNN. It's unknown whether it would be a test or a strike.
As the bombast reaches a fever pitch, the United States is refining its message toward North Korea. The Pentagon now says it is working to decrease the temperature as it maintains a frank and vigilant stance toward Pyongyang's threats.
"We are trying to turn the volume down," a Defense Department official said.
At the same time, National Security Council spokeswoman Caitlin Hayden said, the United States urged North Korea's leaders "to heed President Obama's call to choose the path of peace and come into compliance with its international obligations."
"Threats and provocative actions will not bring North Korea the security, international respect, and economic development it seeks," she said.
The news emerged as South Korean Defense Minister Kim Kwan-jin told a parliamentary committee in Seoul that the North has moved a medium-range missile to its east coast for an imminent test firing or military drill.
The missile doesn't appear to be aimed at the U.S. mainland, Kim said, according to the semi-official South Korean news agency Yonhap.
Wednesday, the United States announced it was sending ballistic missile defenses to Guam, a Western Pacific territory that is home to U.S. naval and air bases. North Korea has cited those bases when listing possible targets for missile attacks.
The latest developments come amid the disclosure of what one U.S. official calls an Obama administration "playbook" of pre-scripted actions and responses to the last several weeks of North Korean rhetoric and provocations.
Pyongyang delivers a warning
Pentagon officials, while decrying North Korean saber-rattling, said recent announcements of U.S. military deployments in response to belligerent statements by North Korea may have contributed to the escalating tensions between the countries.
"We accused the North Koreans of amping things up, now we are worried we did the same thing," one Defense Department official said.
The latest tough talk from Pyongyang lashed out at the U.S. military presence in the region.
A spokesman for a North Korean group accused the United States of "hurling" its "nuclear war hardware into the region and pushing the situation on the brink of war," Pyongyang's official news agency reported.
"The U.S. imperialists have pursued ceaseless war moves since their occupation of South Korea, creating a touch-and-go situation several times. But never have they worked so desperately to launch a nuclear war against the DPRK with all type latest nuclear hardware involved as now," a spokesman for the National Peace Committee of Korea said in a written statement. The DPRK stands for the Democratic People's Republic of Korea.
The statement said the United States is "seriously mistaken if it thinks it can frighten the DPRK with such latest weapons." It said "the country will no longer remain a passive onlooker to the U.S. imperialists' frantic moves to ignite a nuclear war."
"Cutting-edge weapons are not a monopoly of the U.S. and gone are the days never to return when it could invade other countries with nukes as it pleased," the statement said. "The U.S. and the South Korean warmongers had better stop their rash actions, deeply aware of the gravity of the prevailing situation."
The movement of missiles
The movement of the North Korean missile is "of concern, certainly to the U.S. military and to Japan," said Mark Fitzpatrick, director of the Non-Proliferation and Disarmament Programme at the International Institute for Strategic Studies in London.
He said he believes the missile in question is a Musudan, a weapon the North hasn't tested before that is based on a Soviet system with a range of about 2,400 kilometers (1,500 miles), far enough to reach Japan but not Guam. Another worry is that the missile's flight path could pass over Japan, straining nerves in an already jittery region.
The North has medium-range ballistic missiles that can carry high explosives for hundreds of miles. U.S. Defense Secretary Chuck Hagel said Wednesday that the recent North Korean threats to Guam, Hawaii and the U.S. mainland have to be taken seriously.
The medium-range missile will probably take about two weeks to prepare, Fitzpatrick said, which means a potential launch could coincide with the April 15 anniversary of the birth of Kim Il Sung, the founder of North Korea and grandfather of its current leader, Kim Jong Un.
The U.S. playbook
As a result of the war of words, the Obama administration established a "playbook" of pre-scripted actions and responses to the last several weeks of North Korean rhetoric and
