Watching Noam Chomsky on "Democracy Now" just now, talking among other things about the Doomsday Clock–that symbolic clock maintained since 1947 by members of the Atomic Scientist's Science and Security Board at The University of Chicago to represent the measure of danger humanity faces from nuclear war, and now from climate change–and how the clock is now set at 2 1/2 minutes to doomsday, one of the most precarious, alarming settings in recent history.
In regard to the present leadership of the US, the best I can do to make sense of it is to see it is a reenactment of the Cold War. The leadership is nostalgic, having no more than a 5th grader's worldview, informed by the times they were told as 5th grade students to dive under their school desks if and when Russia dropped the big one. All grown up now and in power, their relationship with Russia is certainly different than it was back in the day, much more friendly, cozy even, and so other enemies must be found to fulfill the satisfyingly familiar notion of American superiority.
Thinking of present leadership as re-enacting a sitcom of the 1950's is somewhat comforting, as the memory of Kubrick's film, "Dr. Strangelove", is not.
Nor is something Chomsky said when the present leadership first assumed power, January, 2017: "The Republican Party is the most dangerous political organization in history."
