The particular issue of concern to me is the issue of ground troops. We're not going to defeat ISIL strictly from the air.

I think it's very important to be as clear as we can with the North Koreans about what the rules of engagement are.

I share my colleagues' concern that we are facing a new round of challenges around the world and we really have to revisit that decision.

I would hope that our rules of engagement can be rather clear in order to avoid the possibility of hostilities inadvertently escalating.
