Fareed speaks with Doug Saunders, an international affairs columnist for 'The Globe and Mail' and the author of 'The Myth of the Muslim Tide: Do Immigrants Threaten the West?' about the question of whether there is widespread anger among Muslims in Europe. Watch the full interview on GPS this Sunday at 10 a.m. and 1 p.m. ET on CNN.

What about the general idea that these immigrants, that Muslim immigrants in Europe, are angry, that they are angry with the world, angry with the fact that the world isn't of their making, that the West is sort of the dominant power, that there is a kind of rage, a Muslim rage in Europe?

No. We do need to understand that there obviously are some people among that community who are very angry. The people who are committing anti-Semitic attacks and attacks on journalists and acts of terrorism – these are obviously individuals who are motivated by anger.

The question is, does that reflect the community around them? Is that born out of the community around them, or is that something that's imported, that's a foreign value that they've adopted as a political movement?

And what's interesting is that Muslim communities in Europe, despite being marginalized economically and educationally, tend to be among the most contented with their lives of any minority group, often more so than the general population. There's not a measurable level of discontentment with the society around them or with the lives they lead among Muslims in Europe compared to other groups. It simply isn't something that exists in the larger population.

Fareed speaks with former CIA Director Leon Panetta about how the U.S. should respond to the recent terrorist attack in Paris. Watch the full interview on GPS this Sunday at 10 a.m. and 1 p.m. ET on CNN.

There are a lot of people who feel that the United States doesn't face quite the same danger, partly because, as you say, we've got oceans and watch lists. But also because the Muslim population in the United States is much more thoroughly assimilated than in Europe. Would you agree with that?

Well, I think obviously that since 9/11, we've done a very good job of being able to improve our intelligence gathering capabilities, our law enforcement capabilities, our intelligence in terms of being able to track the particular threats that are out there. And clearly our Muslim population has the opportunity to become citizens in this country, to integrate more fully into our society. And that gives us an advantage.

But having said that, the reality is that when these foreign nationals are able to come back into our country – and there are thousands of these nationals that are overseas in Syria and Iraq, in Yemen – I think it still represents a real danger in terms of the United States.

I don't think we can take anything for granted. I think we're dealing with a much more aggressive form of terrorism coming at us in a number of different directions, as I said. And the United States ought to continue to remain very vigilant and very aggressive in going after this kind of terrorism.

Would you expand the no-fly list, the watch lists? Would you put in place new procedures for even more intrusive intelligence, intelligence gathering?

You know, one thing I learned as CIA director is that you can always improve what you're doing in terms of being able to develop, not only the lists, but develop the intelligence that's needed in order to make sure that we're able to track these individuals. FULL POST

Fareed speaks with former CIA Director Leon Panetta about whether there was an intelligence failure over the attacks in Paris last week. Watch the full interview on GPS this Sunday at 10 a.m. and 1 p.m. ET on CNN.

What was your sense of the quality of French intelligence? I mean one often hears that not only are they pretty good, but they're pretty aggressive. Would that be your sense?

Panetta: Well, there's no question that, I think, the failure to be able to have prevented the attack that took place in Paris was an intelligence failure. And I know they had these individuals on watch lists. I know that, in some ways, they were tracking them, but because of priorities or because of resources, obviously, they weren't aware that these attacks were going to be conducted.

On GPS this Sunday: Fareed offers his take on whether the calls for U.S. military intervention in the Middle East would help prevent the kinds of attacks seen in Paris last week.

Then, Fareed digs deeper into the issue with Leon Panetta, former Director of Central Intelligence, who looks at the terrorism threat in Europe, whether the United States is vulnerable as a target and what the U.S. should do to try to stop something similar happening here.

“You know, I think that what we've seen happening over these last few weeks, between what happened in Ottawa, what's happened in Paris and now what's happened in Belgium, is that we're entering a new and perhaps more dangerous chapter in the war on terrorism,” Panetta says.

Also on the show, Fareed speaks with Doug Saunders, an international affairs columnist for The Globe and Mail and the author of The Myth of the Muslim Tide: Do Immigrants Threaten the West? about claims there has been “an influx" of people from Muslim countries, and that they aren't assimilating into their host countries when they get there.

Plus, Fareed speaks with Malcolm Gladwell, who wrote in support of the broken windows theory in his famous book The Tipping Point, and Bernard Harcourt, who wrote a book called Illusion of Order: The False Premise of Broken Windows Policing, about that much-talked about issue.
