I came across this article at nytimes.com. It says that South Korea wants to take a hard-line approach to North Korea's proliferation of nuclear weapons.
``Our commitment to a denuclearized Korean peninsula is ... clear. As to our position that North Korean nuclear capability can by no means be tolerated -- this issue must be resolved peacefully through the six-party talks,'' said Roh, referring to negotiations that involve both Koreas, China, Japan, Russia and the United States.
This article also talks about how President Roh avoided questions regarding the IAEA report on South Korea's nuclear proliferation. The tensions between North and South Korea seem to be heightening to an even greater level.
