North Korea test-fired a missile in the morning of April 16, right before the U.S. Vice President Mike Pence set foot in South Korea. The No. 2 figure in the Trump administration made a three-day visit to South Korea in the afternoon of the day.
North Korea's latest missile provocation, following the display of three new intercontinental ballistic missiles on April 15, the birthday of the state founder Kim Il-sung, can be interpreted as its desire to show off the strength of the regime, as well as to find out the real intention of the United States and China.
The South Korean Joint Chiefs of Staff announced on the day that North Korea fired an unidentified type of missile from Shinpo but the launch appears to have failed. Five days ago, North Korea had fired a ballistic missile from the same location which flew about 60 kilometers and dropped to the East Sea.
Some security experts said that North Korea's missile provocation is an attempt to show off its military strength against the United States, indicating that it would continue to develop missiles as scheduled no matter what pressure the United States would mount.
