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.

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.

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.

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.

When we use the word domestic [terrorism], we discount its actual impact as political terrorism, which is, of course, political violence meant to impact an audience outside of the immediate victims.

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.
