South Korea says raises cyber security alert level – Yonhap

The alleged hydrogen bomb test by North Korea has set tongues wagging.

U.S analysts tracking China-North Korea relations think China would not squeeze Kim Jong-un’s regime to the point where it may collapse and cause turmoil at its borders.

“A hydrogen bomb would be far more powerful, and more fearsome, than the type of nuclear weapon the North has tested three times since 2006…”

The vast majority of North Korea’s business dealings are with China, which bought 90 per cent of the isolated country’s exports in 2013, according to data compiled by South Korea’s International Trade Association. The US and United Nations have also announced that they’re working on sanctions against the North as a punitive measure.

Philip E. Coyle III, the nuclear expert who directed the Cannikin test, said the seismic signature of the Pyongyang test was “low enough so that it will be hard to tell if the device was boosted, thermonuclear, just fission or whatever”.

Washington (CNN)U.S. Secretary of State John Kerry publicly took issue with China’s policy towards its neighbor North Korea on Thursday and defended the U.S. handling of the crisis sparked by Pyongyang’s nuclear test earlier this week.

North Korea has been developing a missile program over the past few decades, which has grown from artillery rockets to short- and medium-range ballistic missiles.

South Korea’s loudspeaker broadcasts aimed at North Korea are pushing the rivals to the “brink of war”, a top North Korean official has told a propaganda rally.

The August 25 agreement ended an extended and increasingly hostile standoff that had brought the two Koreas to the brink of an armed conflict.

North Korea will likely see the landing as a threat.

Prime Minister Shinzo Abe on Friday questioned Pyongyang’s claim that it tested a hydrogen bomb, noting that the blast appeared to be too small.

The UN has agreed to draw up new measures against North Korea.

“We have to be bigger than the North Koreans”, he said.

The Times reported it could take weeks before the USA can determine more specific details of the test.

The North’s 2013 test produced an estimated yield of 6-7 kilotons of explosives, according to South Korean officials.

But U.S. and other officials expressed deep skepticism about the claims.

It’s unclear why North Korea chose to conduct another nuclear test now.

To build its nuclear program, the North must explode new and more advanced devices so scientists can improve their designs and technology.

“Tunes heading north across the 4km demilitarised zone towards North Korean frontline positions included recent upbeat dance hit Bang, Bang, Bang and a girl band offering featuring the lyric: ‘We’re both so shy/But I wanna go closer to you'”.

US aircraft created to detect evidence of a nuclear test, such as radioactive particulate matter and blast-related noble gases, could be deployed from a USA base on the Japanese island of Okinawa.
