I like all of it (courtesy of WaPo):

South Korean President Lee Myung-bak said today that he will propose setting up a high-level diplomatic channel between North Korea and South Korea, including creating the first liaison offices in the two nations’ capitals. [Snip]

Lee has said that the relationship between the two countries must take a back seat to eliminating North Korea’s nuclear weapons programs, a significant shift from the more conciliatory policy of his predecessor [Boldface mine.] [Snip]

“Both North and South Korea must change their ways,” Lee said. “It is not sufficient for North Korea to resort to their old ways.”

To that end, he said, he wanted to establish a permanent channel so the two countries could have a regular dialogue, rather than intermittent contacts elicited by crises. He said that offices should be headed by officials with direct access to the leaders of each country.

“Between the two Koreas we need to always have dialogue going on,” Lee said. “In the past, we had dialogue between the two Koreas whenever there was a need, and when there wasn’t a need, the dialogue would close. I don’t think that is helpful.”

Yes, by all means, talk to them, but be tough — and it looks like President Lee has been and will continue to be so. His policy, so far, shows all the signs of a real engagement (per Richardson earlier).
