It should be said, however, that the Obama administration so far has failed to stop the advance of nuclear North Korea. Since Obama has been president Pyongyang has conducted two underground nuclear explosions and several missile tests prohibited.

It is not in any way to exclude the possibility that North Korea fail to complete an attack on a ship in South Korea or the respective border. These types of attacks have already been conducted in 2010 with the sinking of a South Korean warship and the shelling of South Korean island.

Assuming that these attacks occur, triggered in what has been called a "Retaliation Proportional" in hopes of avoiding an escalation of the conflict.

Perhaps the hope of Pyongyang is just to get a renegotiation of the sanctions that were imposed by the UN or to get food aid to which so much needs.

In the turmoil created by the provocations that have had such prominence in the media, it should be noted the silence of President Obama.

The President of the United States has failed to respond personally to threats from North Korea, a strategy aimed at depriving Kim Jong-un the "presidential attention."
