Unification is not our present goal. That is a future program.

And also, we are providing, you know, a nuclear power plant in the north, two light water systems, so some 4 or 5 billion dollars we are providing to meet with North Korean requests on the condition North Korea will not produce a nuclear weapon.

If America would withdraw from South Korea, there could be a power struggle between such as China and Japan.

So South Korean ability is very much limited to handle North Korean, you know, difficulties. So we don't want to see an immediate collapse of the North Korea regime.

American presence is, you know, the major cause of balance of power and the stability in this region.

Well, that is very imperative to let North Korea open door to outside.

There is some sign that North Korea is changing recently. There is ongoing successful negotiation to have a military talk to Pyongyang, which has been stopped for seven years.
