Well, I'm not an intelligence expert, and I don't want to even pretend that, but I'm sure there is a sincere interest in somehow or other checking them, and there's no country that has greater experience on it than Israel.
ISIS is a major problem, but with the looting I would also think that they are not the only problem. There's a whole bunch of terrorist organizations, and this is a massive struggle. I don't know that anybody has “the” answer to it. There's probably a combination of things, but certainly for a group like that that has no reverence for life and, in fact, a disdain for life, it's a very difficult battle, but the only way that you can fight them is with strength and firepower to basically remove them. It's as simple as that.
On strategies to do that, the people who have been in this crucible now for quite a long time are the ones who are probably best able to answer that question.
