Domestic terrorism is here, and transnational terrorism is now more scary than before because of a) the rate at which threats are arising and b) amount of time AQ and affiliates are organizing attacks on the homeland. Security agencies can counter this by following Walid's advice by increasing the rate at which we develop our protection and prevention measures (i.e. database management) and amount of time we institute training initiatives.
To aid this process, agencies have the opportunity to couple internal training with a strong recruitment campaign that broadens the pool. However, as Walid also notes, operating procedures need to be (re)defined to identify who among the acting and recruitment pool can access levels of security information. A successful strategic plan will rightly incorporate a structure for information sharing, which I call "bubblenet intelligence."
Such steps should begin simultaneously as President Obama's investigation is being conducted. The jihadi 20-year plan is entering a new phase, one I think we will see unfold at an increased rate over the next 1-2 years simply because AQ believes we are a) internally vulnerable and b) slow to counter. Of course, our activity in Afghanistan, Iraq, and Yemen, along with our (strained) diplomatic efforts with Iran, China, and Latin America, fuels their responsive activity.
Above all, what I think Walid is saying is that national security and international security agencies - in collaboration with one another - need to be more proactive in nature. A system needs to be implemented to ensure this transition, and I think it begins by understanding a strategic analytical framework for realistically quantifying religious radicalization. Furthermore, and perhaps one of the most important aspects of this training effort, is civic engagement with religious leaders. Community engagement promises a) steady growth of unity of mission as well as b) the ability to adapt to emerging scenarios while c) collecting sound intelligence to proactively stay ahead of the enemy at a successful rate for an extended amount of time.
