"They bang the spoon on the table and then suddenly they get food aid. Or they get other concessions. And then they come back to the table and negotiate a little bit, and then if they get bored they start- provocative actions again. We've broken that pattern. Now, what we need to see is whether they're willing to come in a serious way to negotiate these issues." This is what President Obama said on ABC's 'Good Morning America' on the 13th. North Korea should take some confidence building measures to break the cycle of confrontation, which would prompt the US and other players in the frozen six-party talks to respond. They could start by ending nuclear testing. They could start by ending some of this missile testing. There is a whole battery of confidence-building measures that they could engage in. One thing the US must do is to make sure that North Korea is not being rewarded for bad behavior.
