North Korea missile launch would be `huge mistake`: Kerry
US Secretary of State John Kerry demanded North Korea abandon an expected missile launch as the communist state threatened a nuclear strike on Japan.
Seoul: US Secretary of State John Kerry on Friday demanded North Korea abandon an expected missile launch as the communist state threatened a nuclear strike on Japan amid a chilling new evaluation of its offensive capability.
Kerry, visiting Seoul to give fulsome US backing to military ally South Korea, joined President Barack Obama in decrying North Korea`s incendiary rhetoric -- and urged China to step in.
The air of crisis that has engulfed the region for weeks, since North Korea staged a rocket launch and atomic test, was given even greater menace from a US intelligence report that said it may now have a nuclear warhead in its arsenal.
US and South Korean military officials downplayed the assessment by the Defence Intelligence Agency (DIA), but Pyongyang warned of the direst results if Japan executes its threat to shoot down any North Korean missile.
The North`s Korean Central News Agency said that such a "provocative" intervention would see Tokyo -- an enormous conurbation of 30 million people -- "consumed in nuclear flames".
"Japan is always in the cross-hairs of our revolutionary army and if Japan makes a slightest move, the spark of war will touch Japan first," KCNA said in a commentary.
Unbowed, an official at Japan`s Defence Ministry told a news agency that the country "will take every possible measure to respond to any scenario", while Kerry warned that a North Korean missile launch would be a "huge mistake".
"The rhetoric that we are hearing from North Korea is simply unacceptable by any standards," he told a news conference in Seoul alongside South Korean Foreign Minister Yun Byung-Se.
"The United States, South Korea and the entire international community... are all united in the fact that North Korea will not be accepted as a nuclear power," Kerry added.
"If (North Korean leader) Kim Jong-Un decides to launch a missile, whether it`s across the Sea of Japan or any other direction, he will be choosing wilfully to ignore the entire international community.”
"It will be a huge mistake for him to do that because it will further isolate his country," Kerry said, adding that North Koreans want food, not a leader "who wants to flex his muscles".
Kerry also that it was high time for China -- whose trade and aid have propped up North Korea since the end of the Cold War -- to intervene with its wayward ally if it truly wants to safeguard regional stability.
"China has an enormous capability to make a difference here," he said.
Intelligence officials in Seoul say the North, as a show of force, has two mid-range missiles ready for imminent launch from its east coast, and South Korea and Japan remained on heightened alert for any test.
Pyongyang has not officially announced plans for a launch, but a state body in charge of inter-Korean exchanges stressed Thursday that "powerful strike means" were in place.
Observers believe a launch is most likely in the build-up to Monday`s anniversary of the birth of late founder Kim Il-Sung, for which celebrations are already well under way in Pyongyang.
The mid-range missiles mobilised by the North are reported to be untested Musudan models with an estimated range of up to 2,485 miles (4,000 kilometres).
That would cover any target in South Korea and Japan, and possibly even US military bases on the Pacific island of Guam.
Obama said earlier that "nobody wants to see a conflict", but emphasised that the United States was ready to take "all necessary steps to protect its people" and defend its allies in the region.
"We both agree that now is the time for North Korea to end the kind of belligerent approach that they`ve been taking," Obama said after White House talks with UN Secretary General Ban Ki-moon.
North Korea has no proven capacity to shrink a nuclear device onto a missile tip. But for the first time, the DIA evaluation gave official US credence to Pyongyang`s claim in February that it has now mastered the technology.
"DIA assesses with moderate confidence the North currently has nuclear weapons capable of delivery by ballistic missiles," said the report cited by a Republican lawmaker at a congressional hearing. "However, the reliability will be low."
But Pentagon spokesman George Little said it would be "inaccurate" to suggest North Korea had shown that it has such expertise, in a remark echoed by Director of National Intelligence James Clapper.
South Korea was also sceptical. Defence Ministry spokesman Kim Min-Seok said it was "still doubtful" that the North had produced a ballistic missile warhead.
