As reported by Zero Hedge, North Korea now states:

…we have demonstrated our ability to fire our intercontinental ballistic rocket at any time and place and that the entire U.S. territory is within our shooting range.

…Melissa Hanham, a researcher at the James Martin Center for Nonproliferation Studies in California, confirmed the findings saying that the test showed North Korea is now capable of hitting U.S. cities such as Denver or Chicago.

Essentially, Kim Jong-Un just declared, "All your base are belong to us."

Washington D.C. appears to be just out of range for the moment, as the missiles fly over the North Pole and enter the atmosphere over the Northwest portion of the United States. This means Miami is the farthest away from North Korea's reach. Houston, New Orleans and other Southern cities are also on the extreme edge of potential range.

Tensions are escalating, and North Korea could launch an actual attack at any time

In a show of force, the United States Air Force is currently running supersonic bomber drills over North Korea, and President Trump is warning that world that the United States can "no longer allow" North Korea to continue threatening the world with nuclear missile launches that might set off World War III.
