Did North Korea detonate an H-bomb?


North Korea announced it successfully carried out a hydrogen bomb nuclear test on Wednesday, raising concern and doubt across the rest of the world.

H-bombs are hundreds of times more powerful than atomic bombs. Both are kinds of nuclear bombs, meaning that the energy comes from nuclear reactions. Atomic bombs use nuclear fission, which splits a bigger atom into two smaller ones; Hydrogen bombs use fusion, which fuses two or more atoms into a bigger one.

If true, this would be the first test of its kind by North Korea, an isolated and antagonistic regime led by “supreme leader” Kim Jong-un.

World powers, including the United States and South Korea, say they are skeptical of whether the bomb was actually a hydrogen bomb.

Condemnation from nations around the world included North Korea’s only major ally, China. The United Nations Security Council said it will take swift action and will work on a new resolution in response to North Korea’s announcement.

This is North Korea’s fourth nuclear test in violation of international law regarding the spread of nuclear weapons.

Key Terms
