North Korea

So is it saber rattling again or will North Korea make a big mistake?
There have been years and years or threats made and bold moves of defiance directly against the United Sates to provoke war yet nothing more that talks have been the outcome.
What has changed? Why should we take these threats any more serious that the others in the past?

The difference now is the acquisition of atomic weapons WMD’s.
The election of a Liberal Democrat as President is a good sign to world tyrants their threats will be appeased rather than dealt with.
Western foreign policy of be my friend.
The suggestion that within the first six months of the presidents first term he will be tested.
Kim Jong Il is dying and there is a power struggle of which one of his sons will be the next tyrant to rule.

All the ingredients indicate something has changed and the threat may become a reality.
His sons have to prove they can rule. They have to win the respect of the military.
How far will they go to prove this?
They have canceled the 1953 truce.
They are actively testing atomic weapons and delivery systems.
Will North Korea make the same mistake Japan made in 1941?
Time will tell.
