I am not sure the West has the will to enforce it - certainly judging by recent events in Afghanistan where there seems to be a limited amount of support for the USA. The deciding factor might be China's position on the matter. It provides quite a bit of support for North Korea and whether the USA would want to get dragged into a conflict that might escalate beyond the Korean peninsula remains to be seen. Having said that I don't think there is a significant risk of serious conflict since it is in China's long term interest to keep some form of low-level conflict with the USA or its allies going in the area, if only to further its territorial ambitions with the Spratly Islands, http://en.wikipedia.org/wiki/Spratly_Islands http://en.wikipedia.org/wiki/Spratly_Islands and other parts of the South China Sea which apparently has significant old reserves.
