North Korea has launched a ballistic missile, the Pentagon confirmed Tuesday. 

On the surface it seems like more of the same: North Korea responds to another threat by U.S. President Donald Trump by calling him a “deranged” old man who will “pay dearly” for his insults.

North Korea's foreign minister has described President Donald Trump's threat to destroy his country as "the sound of a dog barking." 

South Korea's Defense Ministry said Monday that North Korea appeared to be planning another missile launch, possibly of an ICBM, to show off its claimed ability to target the United States with nuclear weapons, though it was unclear when it might happen. 

South Korean and Japanese officials said North Korea fired four banned ballistic missiles on Monday that flew about 620 miles, with three of them landing in Japan’s exclusive economic zone.
