There is a different future that is available to North Korea, if they choose differently.

So the president set out the policy guidance and said it had to take place in a multilateral fashion so that other countries in the region could be invested in the success of this process.

Now North Korea certainly is located in a different place geographically, but I think it faces the same type of strategic decision. Does it want a different future for its people?

You have to play the cards you are dealt and if it has made it harder, it doesn't matter, you still have to get the deal done.

The nexus between terrorism and nuclear weapons, or even nuclear material, is obviously a current concern.

The other countries did not share the same concern the United States had in the early '90's - that North Korea actually had an ongoing nuclear weapons program.

But with lots of good ideas, implementation is the key, and so we need to keep our eye on the ball as we go forward and make sure that people honor their pledges in terms of financial commitments, and that we actually use this money so that it makes a real difference.
