I totally agree .. they are a paper tiger EXCEPT .. they do have nuclear capabilities .. and they could make a terrible mess - a mess the rest of the world would have to clean up.
Actually, the only evidence that NK has nuclear capabilities is its own declaration in 2009 that they had "A" nuclear weapon....which I don't believe.
Even if they did have A nuclear weapon, SK now has a missile defense system installed that would halt any incoming launched missile from NK.
The Korean war was nasty, with both sides fighting with pretty much the same weaponry and ultimately ended with a cease-fire treaty.
SK and the rest of the civilized world have advanced beyond that day and have created economies that allowed them to continue to militarize to the extent of their needs. NK has not and thus is burdened with antique weaponry and air force and in the event of an actual combat, they would be like high school football players going up against an NFL team.
All the video accounts we see of military parades in NK are propaganda aimed at their own population.
I think it's time that SK says "bring it on" and put an end to all the crap NK has been trying to stir up.
For those who think that China will come to their defense, what does NK have that China would risk going to war with the US and SK considering that China would be throwing away over $400 billion per year in export money to the US...........
