Here is a presentation titled, War and Peace in the Age of Trump, by former Congressman and Budget Director in the Reagan administration, David Stockman, in which he points out some “inconvenient facts” and explains “the warfare state” and the “false narratives” that it promotes to shape public opinion.
Among other things, Stockman point out that there is no existential threat to the United States that would justify the massive U.S. military-industrial-intelligence complex, the policy of regime change, and interventions in the Middle-east, Africa, and all around the world. Even the the recent acts of terrorism and the refugee crisis in Europe are blowback from the mayhem that the U.S. and NATO have been unleashing in those regions.
Edit: Paul Craig Roberts adds some further important details to the picture.
