North Korea claims they have a hydrogen bomb and the world shrugs
Through the state-run Korean Central News Agency (KCNA), Kim Jong-Un, North Korea's supreme leader, announced his country is "ready to detonate a self-reliant A-bomb and H-bomb to reliably defend its sovereignty and the dignity of the nation." American and South Korean officials are dismissing the claim.
"The information that we have access to calls into serious question those claims, but we take very seriously the risk and the threat that is posed by the North Korean regime in their ambitions to develop a nuclear weapon," said White House press secretary Josh Earnest.
Kim made the announcement while inspecting an historical military site in Pyongyang. The regime first became a confirmed nuclear power in 2006 under Kim's predecessor and father Kim Jong-Il when North Korea detonated the first of three nuclear bombs.
North Korea's regime detonates nukes at "secret" underground nuclear tests sites. The announcement comes on the heels of the discovery of new nuclear testing tunnels, uncovered by satellite photos, at Punggye-ri in the northeast area of the country.
This is the first time the Kim regime claimed to have hydrogen bomb technology and the announcement may be a response to the recent U.S. sanctions targeting North Korea's Strategic Rocket Force and banks involved in North Korean arms proliferation.
North Korea has a history of acting out in response to Western actions it sees as provocative. When the U.S. and South Korea performed its yearly joint Foal Eagle exercise in 2015, the North launched two scud missiles into the sea outside of South Korea. When the South conducted a combined arms exercise near Baengnyeong and Yeonpyeong Islands near the maritime border with the North, North Korean artillery batteries shelled the island for an hour.
The North is not yet able to put a nuclear weapon on one of its rockets, but its nuclear capabilities do threaten U.S. allies in the region.
"We don't have any information that North Korea has developed an H-bomb," a South Korean intelligence official told the South's Yonhap News Agency. "We do not believe that North Korea, which has not succeeded in miniaturizing nuclear bombs, has the technology to produce an H-bomb."
North Korea claimed in 2010 that it had successfully developed fusion technology.
