600 miles of range is hardly, "Intercontinental". This was a short or theater range missile at best, not an ICBM, by a long shot.

Missiles are classified as follows:

Short-range ballistic missiles, traveling less than 1,000 kilometers (approximately 620 miles)

Medium-range ballistic missiles, traveling between 1,000–3,000 kilometers (approximately 620-1,860 miles)

Intermediate-range ballistic missiles, traveling between 3,000–5,500 kilometers (approximately 1,860-3,410 miles)

Intercontinental ballistic missiles (ICBMs), traveling more than 5,500 kilometers.

North Korea only has tested one "Intercontinental Ballistic Missile", The Taepo Dong-2, 3-stage unit. This missile has an estimated 4,500 kilometer stated range. However it should be noted that the Pentagon has stated that this missile is intended as a satellite launch vehicle and not a ballistic missile.

After several failures, a successful launch of a Taepo Dong-2, 3-stage unit (Unha-3), occurred in December 2012 with the launch of the second version of Kwangmyŏngsŏng-3 satellite. The North repeated this success with the launch on February 7, 2016 of Kwangmyŏngsŏng-4 satellite.

North Korean has no Ballistic Missiles capable of reaching the United States that are armed and ready as a combat system. It's largest rocket is for launching satellites.

Countries fire test missiles all the time, this is hardly news and the fact that it is treated with importance says more about the lazy press and U.S. Propaganda, than anything else.

No doubt that North Korea is a bad place, run by bad people. The U.S. and the International community shouldn't have to make up fake news to make them look bad.
