Pentagon chief James Mattis says any threat to the US or its allies by North Korea will be met with a “massive military response”.
His comments came after a national security briefing with President Donald Trump about North Korea’s latest nuclear test.
North Korea claimed it had successfully conducted its sixth and most powerful nuclear test, detonating a hydrogen bomb that could be loaded onto a long-range missile. But speaking to reporters outside the White House, Defence Secretary Mattis said the US had the ability to defend itself and its allies South Korea and Japan.
“Any threat to the United States or its territories – including Guam – or our allies will be met with a massive military response, a response both effective and overwhelming.” However, he said the hope was for denuclearisation, “because we are not looking to the total annihilation of a country, namely North Korea”.
North Korea has defied UN sanctions and international pressure by developing nuclear weapons and test missiles that could potentially reach the US. On Sunday, seismologists’ equipment started picking up readings of an earth tremor in the area where North Korea has conducted nuclear tests before.
The US Geological Survey put the tremor at 6.3 magnitude. Japanese Foreign Minister Taro Kono said there was no doubt this was North Korea’s sixth nuclear test, calling it “unforgivable”. Then North Korean state media confirmed it was indeed no earthquake and claimed the country has conducted another nuclear test in spite of warnings not to. North Korean leader Kim Jong-un was pictured with what state media said was a new type of hydrogen bomb. Hydrogen bombs are many times more powerful than an atomic bomb.
They use fusion – the merging of atoms – to unleash huge amounts of energy, whereas atomic bombs use nuclear fission, or the splitting of atoms. The latest move by North Korea has drawn international condemnation. The UN Security Council is to hold an emergency meeting on Monday to discuss an international response, according to the US mission.
