This is a perfect example of the completely wrongheaded, even stupid, approach to North-South relations in South Korea. What is needed is South Korean propaganda in the North, not North Korean propaganda in the South.
I defy anyone to explain to me just how Samsung's move will do a single concrete thing to "improve relations with the North". How many DPRK Divisions will pull back from the DMZ as a result? How many prison camps will close? How many South Korean television channels will be carried in the North?
As I thought.
It is a gimmick geared for S. Korean population. For Samsung, it rides the touchy-feely 'reconciliation' bandwagon to push its products, while the government tries to get political mileage by showing that everything is hunky-dory even though N. Korea might set off a nuke soon.
However, it does nothing to change N. Korean behaviors, as you said. Plastering N. Korean babe's image on screen sure got many sheeple excited.
To some airheads, the reconciliation with N. Korea is nothing more than getting to like N. Korean dancers, entertainers or some smooth-talking officials, but not worrying about the plight of poor miserable haggard peons.
Maybe they can send a "specially equipped" cell phone to Mr. Ronery himself, and give him a wake-up call with it.
