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."

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.

Trump wants to be an autocrat, he does want to be a Vladimir Putin-style ruler. His chief strategic advisor, Steve Bannon, is a follower of Alexander Dugin.

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.

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.
