Well, I'd say frankly all the countries that have bred Islamic extremist groups. Obviously many of those would be concentrated in the Middle East and North Africa, but I want to bring to the committee's attention also groups that originate from Latin America.
I've done quite a bit of research on the presence of Islamic extremism in Latin America, which has grown about tenfold in the last ten years. I would say that there is an element in Latin America that is anti-U.S., anti-west, and anti-Canada as well, known as the ALBA group, consisting of Venezuela, Bolivia, Nicaragua, and Ecuador.
Most of these Islamic extremism groups, including—probably most poignantly—Hezbollah, have penetrated these countries and have used fake Venezuelan passports to enter the United States. I would say to pay special attention to these countries in Latin America.
