There is no difference between an ISIS gunman and an American gunman that goes into a mosque, or the gunman Baruch Goldstein who went into the mosque in Bethlehem and killed 29 guys about fifteen years ago. Goldstein took his service weapon and tried to kill everybody in the mosque. He shot over a hundred people. There's no monopoly on terrorism. Terrorism experts know this and we live according to that.

You can`t differentiate between an Islamic terrorist and a Christian terrorist. Or a politically motivated terrorist who`s anti-abortion or someone who may have differing views.

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.

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.

Trump doesn't understand the counterintelligence process. Take, for example, Carter Page. He's been appearing on television and acting as though the U.S. intelligence community monitoring his activities in Russia and suspicions that he may have been in league with Russian intelligence is an affront.

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.

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.
