Absolutely. There already is. There's a pretty large appetite in the international community for diplomacy to be given a chance. What we have to bear in mind here is that in terms of any other approach there is no effective military response. Any military response is catastrophic. With the level of rhetoric we have, there's really a danger of inadvertent escalation and miscalculation. That's a huge danger, and we need to get that rhetoric down.
If one comes to grips and faces the hard reality, there is no effective military response. I fully agree with earlier comments made by Andrea Berger about the time being past for North Korea to renounce nuclear weapons. She used the term “restraint”. As the Chinese and the Russians have urged, there might be a possibility of measures of restraint, of some form of freezing of the activity.
The final point I would make about the demonstration aspect is that this is classic deterrence. It's North Korea trying to make clear that they have a credible retaliatory capacity. It's very ironic that in fact they're demonstrating the classic deterrence theory as espoused by the nuclear arms states.
