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

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

I think a major cause of present Asian economic difficulties that mainly come from, you know, lack of market economy.

So if North Korea continues present isolation, then with such economic difficulties the North Korean government must meet a very serious situation in the future.

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.

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

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.
