The ghost caliphate will be a virtual organization; it'll be decentralised, with no leadership, and it will just encourage people to keep acting now that the caliphate's gone, that individuals should go do self-starting jihad. Get a gun, get an improvised weapon, take your car, and carry out the jihad.

There`s actually some fluidity here in the United States. Using local intelligence against [terrorism].But you still have to infiltrate these groups. You still have to collect intelligence as you see fit. And they are organized. They are very well organized in the anti-abortion movement. Ideologically, they`re almost the same. And that`s where we see these spurts of violence.

There's only two classes of people: terrorists and non-terrorists. Terrorists come in every flavour: there are Buddhist terrorists right now killing Rohingya in Burma! Buddhists! They're not allowed to kill bugs.

Arson is the single most fundamental form of terrorism.It`s the simplest terrorist tactic.

Law enforcement does counter political extremism here in the United States in the exact same way that they do political extremists who are infiltrated into the United States, who may come from a religious motivation, as we saw overseas in Europe. But the same methodologies have to be used.

ISIS rules Muslim apostates every day and then beheads them. Poorly educated guys get Islam for Dummies, petty criminals who think they're suddenly changing their lives because they see the light. The best way to fight them is to show them they don't know Islam at all, and that they are in fact working for the other side.

ISIS is going to devolve from physical political emirate, into what Al Qaeda was, which is a covert organization which will go completely underground. But to communicate and to keep propagating their propaganda, after everyone is dead, all their fanboys and whatever surviving leadership that has been operating outside the war or operates in Somalia, Yemen, and Afghanistan, they will form what we call a "ghost caliphate."
