One day after North Korea conducted its largest-ever nuclear test, US Ambassador to the UN Nikki Haley says the country's leader, Kim Jong Un, is "begging for war," CNN reports. Haley made the claim during an emergency meeting of the UN Security Council Monday as part of a lobbying effort to convince them to take the "strongest possible measures" against North Korea after the country detonated a thermonuclear warhead underground on Sunday. "Enough is enough," Haley said. "We have taken an incremental approach, and despite the best of intentions, it has not worked." Yesterday Defense Secretary Jim Mattis responded to the latest test by saying the US will answer North Korean threats with a "massive military response — a response both effective and overwhelming."
Experts believe the explosive tested Sunday has a power range of between 50 and 150 kilotons, far larger than the power of the bomb that destroyed Hiroshima at the end of WWII, the BBC reports. Pyongyang claims it has the capacity to reduce the warhead in size and attach it to an ICBM capable of hitting the US mainland, though some analysts remain skeptical. Regardless, Haley said, US patience with North Korea is "not unlimited." "Only the strongest sanctions will enable us to resolve this problem through diplomacy," she told her colleagues on the security council. "We have kicked the can down the road long enough. There is no more road left." (Read more Nikki Haley stories.)
