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 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.

Now you have Donald Trump ready to execute policy on the basis that the Muslims are the problem, not ISIS. Oh Jesus, it's a circular firing squad.

We have this unfortunate habit in the United States of dividing terrorism into different categories. External, foreign terrorism, which manifests itself overseas or in the United States, or domestic terrorism.

Most ISIS members are irreconcilable. Once they've bitten that bug, that cultish bug, they would prefer to die. They're going to be given the opportunity, no one's going to get out alive from Iraq and Syria now. They make sure everyone's a suicide bomber now.

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.
