North Korea Claims It Has A Hydrogen Bomb, Here’s What That Means

North Korea appears to have made a significant leap in its nuclear program over the weekend, dramatically escalating the threat to the U.S. and its allies.

The rogue regime, undeterred by international pressure, conducted its sixth nuclear test Sunday, detonating a possible thermonuclear device with an explosive yield of roughly 150 kilotons, according to the U.S. government. The North’s fifth nuclear test involved a bomb with an explosive yield somewhere between 10 and 30 kilotons. Low-end estimates of the yield of the latest test are around 60 kilotons, while high-end estimates are around 500 kilotons, incredible destructive power.

The test followed the revelation of an improved nuclear warhead for North Korea’s new intercontinental ballistic missile, and it is extremely likely that the North specifically tested this device, leading experts argued in the aftermath.

“What they show us is going to be the real deal, or very true to life,” Joshua Pollack, editor of Nonproliferation Review and a senior research associate in the James Martin Center for Nonproliferation Studies at the Middlebury Institute for International Studies, told The Washington Post.

“Given the closeness in time between the exhibition of the device and the actual test, I wouldn’t be surprised if that was the actual device,” he explained, “They have very good reasons to show exactly what they’ve got, because they’re trying to enhance their credibility. I give them the benefit of the doubt on this one.”

North Korea claims it tested a hydrogen bomb. The U.S. intelligence community reportedly assesses that the North tested either a staged thermonuclear or a boosted fission weapon.

The atomic bombs dropped on Hiroshima and Nagasaki, Japan were fission bombs that released destructive energy by splitting uranium and plutonium atoms. A hydrogen bomb, which only a few countries possess, incorporates both fission and fusion reactions in two separate stages. The fusion stage involves smashing hydrogen atoms together to increase the explosive power in much the same way that the sun is fueled. A hydrogen bomb is significantly more powerful than a traditional atomic bomb or even a boosted-fission bomb, which incorporates a small amount of fusion fuel to accelerate the fission reaction and the boost the explosive yield.

It is unclear whether North Korea tested a boosted-fission device over the weekend or a thermonuclear weapon as claimed. Even if it turns out that North Korea has not yet developed a hydrogen bomb, the North is clearly moving in that direction.

The new warhead North Korea revealed prior to the test indicated that North Korea’s nuclear scientists are not unfamiliar with the designs for thermonuclear weapons, specifically the Teller-Ulam design. In a two-stage configuration, the first stage provides the necessary energy to ignite the second stage.

There are several types of fission-fusion bombs though.

“The most sophisticated [is] a two-stage thermonuclear device, a.k.a., hydrogen bomb,” Pollack explained to The Daily Caller News Foundation, “That’s how they described the device. I have no good reason to question that characterization, but as long as the weapon fits on the missile, it doesn’t really matter exactly how they got to a yield that size, does it?”

The North plans to load a thermonuclear warhead on its powerful new Hwasong-14 ICBM, which expert observers and the U.S. government say has the ability to strike parts of, if not most, of the continental U.S. North Korea has tested this missile twice successfully in July. While this weapon may lack a highly-sophisticated guidance system, as some American defense analysts claim, the missile appears to have what it takes to deliver a devastating nuclear payload to targets across the country.

“This is a city-busting weapon,” Pollack told TheDCNF, referring to the nuclear device North Korea tested Sunday.

“With a thermonuclear weapon sitting atop even an inaccurate ICBM, a single warhead is sufficient to level most of a large American city,” Ankit Panda, senior editor at The Diplomat, and Vipin Narang, an associate professor of political science at the Massachusetts Institute of Technology, explained in a recent post for War on the Rocks.

North Korea is moving towards its goal of a viable nuclear deterrent against the U.S. at an accelerated rate.

Readers,

Instead of sucking up to the political and corporate powers that dominate America, The Daily Caller is fighting for you — our readers. We humbly ask you to consider joining us in this fight.

Now that millions of readers are rejecting the increasingly biased and even corrupt corporate media and joining us daily, there are powerful forces lined up to stop us: the old guard of the news media hopes to marginalize us; the big corporate ad agencies want to deprive us of revenue and put us out of business; senators threaten to have our reporters arrested for asking simple questions; the big tech platforms want to limit our ability to communicate with you; and the political party establishments feel threatened by our independence.

We don't complain -- we can't stand complainers -- but we do call it how we see it. We have a fight on our hands, and it's intense. We need your help to smash through the big tech, big media and big government blockade.

We're the insurgent outsiders for a reason: our deep-dive investigations hold the powerful to account. Our original videos undermine their narratives on a daily basis. Even our insistence on having fun infuriates them -- because we won’t bend the knee to political correctness.

One reason we stand apart is because we are not afraid to say we love America. We love her with every fiber of our being, and we think she's worth saving from today’s craziness.

Help us save her.

A second reason we stand out is the sheer number of honest responsible reporters we have helped train. We have trained so many solid reporters that they now hold prominent positions at publications across the political spectrum. Hear a rare reasonable voice at a place like CNN? There’s a good chance they were trained at Daily Caller. Same goes for the numerous Daily Caller alumni dominating the news coverage at outlets such as Fox News, Newsmax, Daily Wire and many others.

Simply put, America needs solid reporters fighting to tell the truth or we will never have honest elections or a fair system. We are working tirelessly to make that happen and we are making a difference.

Since 2010, The Daily Caller has grown immensely. We're in the halls of Congress. We're in the Oval Office. And we're in up to 20 million homes every single month. That's 20 million Americans like you who are impossible to ignore.

We can overcome the forces lined up against all of us. This is an important mission but we can’t do it unless you — the everyday Americans forgotten by the establishment — have our back.

Please consider becoming a Daily Caller Patriot today, and help us keep doing work that holds politicians, corporations and other leaders accountable. Help us thumb our noses at political correctness. Help us train a new generation of news reporters who will actually tell the truth. And help us remind Americans everywhere that there are millions of us who remain clear-eyed about our country's greatness.

In return for membership, Daily Caller Patriots will be able to read The Daily Caller without any of the ads that we have long used to support our mission. We know the ads drive you crazy. They drive us crazy too. But we need revenue to keep the fight going. If you join us, we will cut out the ads for you and put every Lincoln-headed cent we earn into amplifying our voice, training even more solid reporters, and giving you the ad-free experience and lightning fast website you deserve.

Patriots will also be eligible for Patriots Only content, newsletters, chats and live events with our reporters and editors. It's simple: welcome us into your lives, and we'll welcome you into ours.

We can save America together.

Become a Daily Caller Patriot today.
