North Korea’s state television claimed a successful detonation of what it called a hydrogen bomb on Sunday. It’s the country’s sixth nuclear test. The incident caused a magnitude-6.3 tremor. South Korea responded with a live-fire military exercise on Monday. And last week, North Korea launched a missile that flew over the Japanese island of Hokkaido.

Applying pressure to North Korea’s allies, like China, President Donald Trump threatened in a tweet, “The United States is considering, in addition to other options, stopping all trade with any country doing business with North Korea.” Russian President Vladimir Putin described the current sanctions regime against North Korea as “useless.”
