North Korea's Threat to Attack America Should Not Be Much Concerned

These days media reports the threats of North Korea to attack America with nuclear weapon. Please, don't be overwhelming media! That's just threat, its been long time North Korea plans to attack America, but nothing happens! However, what if North Korea really means it? North Korea will never find the victory! Okay, let me assume it. First, America has developed nuclear weapon long long time ago than North Korea. It means America has greater nuclear technology than North Korea. Second, America has advanced military technology than North Korea. So, once more there is no reason North Korea can win over America. They can only blow nearby America's military bases in the east Asia, if that is possible.
