Nuclear proliferation

America's top diplomat has warned that North Korea is "begging for war" and urged the UN security council to impose the toughest sanctions possible on the isolated dictatorship, The Guardian reported. 

North Korea's determination to pursue its policy of becoming a nuclear power continues to endanger world peace. When Kim Jong-un's photos appeared in the international press jubilating his country's latest test of an alleged hydrogen bomb, the international community condemned North Korea for its "unlawful, irresponsible and adventurous" behavior. South Korea launched its own missile test.

The United States is ready to use its nuclear capability if North Korea continues to threaten US territories or allies, the White House said. After the latest provocative nuclear test in Pyongyang, President Donald Trump held a conversation with Japanese Prime Minister Shinzo Abe. They discussed the assertion that North Korean regime test of a hydrogen bomb.

North Korea is readying the launch of a ballistic missile, military leaders in South Korea believe after launching rockets in live-fire drills in response to the test of a nuclear bomb at the weekend.

NATO Secretary General Jens Stoltenberg condemned North Korea's sixth nuclear test and described it as destabilizing, DPA reported.

North Korea announced it has carried out a hydrogen atom bomb test and called it "absolute success," the BBC reported. The Communist State Television has already broadcast footage to which Kim Jing-nun signs a nuclear warrant.

South Korea and Japan have confirmed that Pyongyang has done its most powerful nuclear experment so far, Reuters reports.

North Korea says it has successfully tested a hydrogen bomb on Sunday. It is its sixth long-range missile test, marking a dramatic escalation of the the regime’s stand-off with the United States and its allies.

The United States wants to know if the United Nations atomic watchdog plans to inspect Iranian military sites to verify Tehran's compliance with a 2015 nuclear deal, the U.S. ambassador to the United Nations, Nikki Haley, said on Aug. 22.

South Korean President Moon Jae-in said on Thursday U.S. President Donald Trump has promised to seek Seoul's approval before pursuing any option against nuclear-armed North Korea, Reuters reported.

Trump's recent aggressive comments about deploying possible military options underscored his resolve to counter the threat from the North's nuclear weapons and missile programs. 

The on-going North Korean nuclear crisis, in addition to the previous nuclear crises with Iraq and Iran, demonstrates that we lack a coherent, peaceful approach to respond decisively to major nuclear proliferation threats.

In all three cases, world leaders have wavered between war and diplomacy. The results have been suboptimal.
