In favor of what Peter Vandever has told us about IHOPKC, they have recently (2017) stated

“We deny that the Church will take over all the governments of the earth before the return of Christ. In this we would differ from others who hold to more of a triumphalist eschatology that many organs of government will become Christianized before the return of Christ.”

This clarifies it plainly. Perhaps Gary can ask Dr Brown for one such statement that could resolve the question. His new book however _leans_ toward dominionism in ways that nobody can tell you otherwise Is this just a coincidence with the 2018 elections?
