It's 5:51am Saturday in North Korea and the celebration of their founders holiday begins, The Day of the Sun.
The reports I read said they always launch a missile on this holiday, if they submit to China's demands, this will be their first Day of the Sun in decades not launching a missile in celebration of their independence.
This is a news report from 2014 about the Day of the Sun holiday and how huge it is in North Korea. @ 1:15 is interesting.
