South Korea’s joint Chiefs of Staff recently confirmed that North Korea launched an unidentified ballistic missile over Japan. Launched from the district of Sunan, the missile flew about 2,300 miles, reached 480 miles in altitude before landing in the Pacific Ocean.

South Korea hosted a “live fire drill” that reportedly “included a missile launch” that was “capable of striking the Sunan airport launch site” in response to North Korea’s launch.

According to CNN.com, “the launch came just hours after the rogue nation responded to the United Nations Security Council’s unanimous approval of additional sanctions by threatening to ‘sink’ Japan and reduce the US mainland into ‘ash and darkness.’”

The sanctions that spawned the missile launch was caused by North Korea’s successful test of a hydrogen bomb on September 3. That test led to an explosion that created a magnitude-6.3 tremor —the most powerful weapon tested North Korea’s capital.

Despite being briefed on the missile launch, President Donald Trump has yet to comment. While POTUS remains silent, US Secretary of State Rex Tillerson called North Korea’s missile launch the second time the people of Japan “have been directly threatened in recent weeks.” “These continued provocations only deepen North Korea’s diplomatic and economic isolation,” he added.
