Korean navies clash in disputed zone (transcript from ABC, Australia on 10/11/2009)

'South Korea's media is reporting that the North and South Korean navies have clashed in the Yellow sea'.
After reading the report, I am convinced that reunification between North and South Korea still has a long long way to go!
My perspective is quite simple; since the secession of two nations after the Korean civil war during 1950's, citizen on South and North Korea is living in a totally different world! North Korean people has been suffering sanctions from the western world and by itself under rulership by a dictator (totalitarian regime). On top of that, citizen from the North also suffering from starvations, poverty as well as livelihood without freedom.
Contrary to the North, South Korean people is luckier as they have been receiving foreign aids from western world during the early 60's after the secession of Korean war. In the meantime, South Korean has been transformed into a democratic nation from late 80's which benefited from the wave of democratization all over the world.
Regardless of their races falls into same ethnic group, but due to great difference on political environment as well as mechanism which will keep both nation apart in the foreseeable future!
