 On April 15, 2017, at the yearly major public holiday also known in the country as the Day of the Sun, North Korea staged a massive military parade to commemorate the 105th birth anniversary of Kim Il-sung, the country's founder and grandfather of current leader, Kim Jong-un.The parade took place amid hot speculation in the United States, Japan, and South Korea that the country would also potentially test a sixth nuclear device, but failed to do so.The parade did publicly display, for the first time, two new intercontinental ballistic missile-sized canisters as well as submarine-launched ballistic missiles and a land-based version of the same.
