The most difficult North Korea riddles

For the initial months of the war, the P-80 Shooting Star, F9F Panther, and other jets under the UN flag dominated North Korea's prop-driven air force. The Chinese intervention in late October 1950 brought MiG-15 Fagot to battle, one of the world's most advanced jet fighters. MiGs were often steered by well trained Soviet pilots, so the aerial warfare continued till the end of the war.

The year isn't 2018. The North Korean or Juche calendar was adopted in 1997 and begins with the year of Kim Il-sung's birth (1912 – or Juche 1 to North Koreans). Which means 2018 in Pyongyang is actually Juche 107.

Kim Il-sung gained military and political education in the USSR. During World War II, he served in the Red Army, commanding a division of Koreans. He was undoubtedly the weakest educated leader in the entire Eastern bloc.
