What kind of foreign policy should be pursued by the Obama team in addressing Iran and N Korea?

There are two ways of looking at it. One way is just to simply say that there is nothing we can do. N Korea seems hell-bent on obtaining nuclear capabilities, and taking action could have drastic fall out on so many countries. Especially with US forces spread out in Iraq, Afghanistan, and Pakistan. N Korea has stated that any resistance would be seen as an act of war. The other way is to say that we have to address the problem now, in case of any future threats. Really, it is somewhat reasonable to think that along the line, action has to be taken if we really want to stop this. N Korea, however, could simply be doing this to feel like they have power. Even if N Korea has a nuclear arsenal, they probably wouldn't use it on other countries willingly because of the obvious ramifications. I think that in the end, N Korea and Iran will get their nuclear capabilities. If they don't, however, that means USA is invading one or the other.
