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.

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.

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.

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."

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.

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.
