@McGentrix,
They don't want to say it, acknowledge it or apparently think about it. Kim Jong Un, came to power on the death of his father Kim Jong Il in late 2011, in the last year of Obama's first term as president. The father, Kim Jong Il ruled the country from 1994, the second year of Clinton's presidency.
The father was very successful in extorting benefits from the United States in exchange for promises, usually ignored, to cut back on a program for the development of nuclear weapons and ballistic missiles which the country had pursued relentlessly and without interruption for the last three decades. During his Presidency G.W. Bush cut off the subsidies and payoffs, but largely focused his attentions elsewhere. The current Kim Jong Ill appears to have learned very well from his father.
The North Korean Nuclear weapons & missile development is now too far advanced to ignore any longer. The piper must finally be paid.
