Sorry David but I cannot agree there as even although the people of North Korea have no democracy, the countries of the world that do should be able to encourage these rogue states to behave themselves.
The three points about North Korea that make me worry are 1), The country is ruled by a military junta. 2). It is not responsible to any other country in the world, ( other than maybe China, who do not want to be seen as interfering ). and 3). They DO have nuclear weapons and the capability to deliver them, and those three things together make them a very dangerous entity.
I don't think that they would ever use these nuclear weapons as if they did they would know that the act of doing so could bring ten times what they could deliver raining down on their heads.
I do agree with Angelo that if we can just wait patiently the greed that is built into Capitalism will bring them down just as it did with the Soviet states and has started to happen already in China.
I just hope that we have the time to see this come about !
