"It's take your daughter to work day" was the rather obvious joke as pictures circulated online of a young girl and her father on what was anything but a typical family outing.

The release Saturday of the photos featuring North Korean leader Kim Jong Un and his daughter observing a missile launch — the first public revelation of the existence of one of his children — overshadowed an accompanying report in state-run media trumpeting the successful test of the country’s most powerful intercontinental ballistic missile (ICBM) to date.

Was this the public debut of “Ju Ae,” the baby daughter of Kim that former American basketball star Dennis Rodman claimed to have held during a 2013 visit to North Korea? If so, why did Kim reveal her to the world now?
