Petraeus gives an interesting interview to Foreign Policy. The interviewer asks whether Iraq and Afghanistan are fundamentally different from prior wars. Petraeus replies:

We looked at this issue closely when we were drafting the counterinsurgency manual. And we concluded that some aspects of contemporary extremist tactics are, indeed, new. If you look, as we did, at what [French military officer] David Galula faced in Algeria, you find, obviously, that he and his colleagues did not have to deal with a transnational extremist network enabled by access to the Internet. Today, extremist media cells recruit, exhort, train, share expertise, and generate resources in cyberspace. The incidence of very lethal suicide bombers and massive car bombs is vastly higher today. It seems as if suicide car bombs have become the precision-guided munition of modern insurgents and extremists. And while there has been a religious component in many insurgencies, the extremist nature of the particular enemy we face seems unprecedented in recent memory.
