there are more dangerous countries such as North Korea and Iran. I like Pakistan 
yesNorth Korea is very dangerous because they are advancing nuclear technology
Even they are more dangerous than the state of america
Not that the Koreans would ever do something with those nukes. The ruling class of feudal communists are simply trying to prolong their control over the country by threatening the South. If they don't do that the two Koreas will eventually unite and we all know which one will dissolve into the other.
