The centralized international leadership and funding able to to put together massive 9/11 style attacks might be finished, at least in that part of the world. But there are other places they could take root, like Somalia, or any mideast country where a protracted rebellion takes place, like Libya. And we'll still have to deal with local nationalist level groups. And we will still get the occasional self-radicalized cell hiding behind a mosque here and there. You might say that now that their hero is sleeping with the fishes, they have nothing to coalesce around, so maybe, just maybe, the worst is over. But its the nationalist groups you have to watch out for. The Muslim Brotherhood is using the Arab Spring to gain pan-Arab political power. Egypt is circling their drain, and they are said to have a hand in Syria as well. If they are allowed to fall, they could attempt a new caliphate, where terrorism against the West is a matter of policy and could spark a third world war. There are also indications that they are working with Iran, representing at least a "temporary" alliance with their Shiite adversaries. Pakistan is also reaping what is has sown, with its own spy agency supporting the Taliban, that is just as much a threat to them as it is Afghanistan. That cancer will continue to pick away civil society in Pakistan, with the civilian leadership and even the Army seemingly unwilling to rock the boat enough to eliminate the threat.
