Swiss journalist Maurine Mercier found several United States citizens fighting in Ukraine under the guise of humanitarian work. These rudderless warriors are a symbol of a society addicted to warfare. They reflect the tensions that author and antiwar activist Norman Solomon unwinds in his brilliant new book, War Made Invisible, which examines the profound causes and costs of U.S. interventionism. Solomon's book unveils the disturbing proximity between the ruling class and corporate media since the Vietnam War, revealing how the fourth estate sustains the assumptions that make intervention possible in Ukraine and elsewhere. "The essence of propaganda is repetition," he argues. "The frequencies of certain assumptions blend into a kind of white noise," conditioning U.S. people to support military operations they never see or truly understand. This was never clearer than during the 2003 invasion of Iraq. Indeed, across the media landscape, embedded intellectuals mobilized their pens to solidify public support for war. ABC, NBC, CBS and PBS all skewed their coverage. In many ways, militarism is a form of class warfare. "The fat profit margins from supplying the Pentagon and kindred agencies," Solomon explains, exacerbate economic inequality while redirecting resources away from social programs. In effect, war is perpetual because it is profitable, enriching an elite firmly entrenched in the military-industrial complex.
