Argument: Providing attention simply encourages the regime

North Korea has an attention seeking cycle on the go that was used by Kim Jong Il and now seems to be used by his son Kim Jong Un. Essentially North Korea takes a provocative action (as big or small as it thinks necessary – this may be a missile launch, right up to some kind of military attack) in order to grab the world’s attention. There is then a period where there are condemnations and threats to increase sanctions that usually don’t get anywhere as they are blocked by China. The North Korean regime will then proclaim a willingness to do business and negotiate giving minor concessions on the issue of the provocation in return for aid or whatever the regime happens to want at the time. Of course whatever concession it gives is easily reversible so setting up another round. [1] This is a good deal for North Korea as it essentially gets aid in return for bad behaviour, it is therefore not surprising that the North is willing to continue engaging in bad behaviour.

Candidate 1: "Pressure from other states acts as a force multiplier helping to show that the North has crossed a line with its actions. A lack of reaction from the Unites States, Japan, and other states around the world would show that these nations are no longer supporting the South as strongly as they were. The United States in particular has to be willing to engage with North Korea in order to present a united front with its South Korean ally."
Candidate 2: "Negotiations to defuse the cause of the immediate tension, and sanctions to encourage North Korea to the negotiating table are sensible, proportionate responses to North Korean actions. It is difficult to see how sanctions can be seen as encouraging even if those sanctions are then eased when North Korea climbs down."
Candidate 3: "The United States has its own interests in the North Korean question, not only does it have troops in South Korea and security guarantees to maintain with its ally but it is also concerned by nuclear proliferation. If there is a chance to get rid of North Korean nuclear weapons through negotiations, or even a peace treaty should the USA not take that when it is in the US national interest? [1]
