I was thinking about Born on the Fourth of July. I did not react well to the depiction of Ron Kovic (played by Tom Cruise) the first few times of watching the movie. His suffering seemed to be expressed as self-indulgent whining. As I've gotten older, I've come to sympathize with him a bit more; he lost much after being duped into imperialism, not patriotism, and his loss was sufficient to provoke a crisis of faith (he seems to have rejected his Catholicism) as a part of existential crisis. Did he ever return to the Catholic faith? Does he offer a solution to war that is not statist? If it is not statist, is it more like an alternative (or false) religion or spirituality with a utopian vision of humanity?
If patriotism requires localism and a true community, then violence may be needed to protect the community -- are more wars likely if the number of self-ruling communities is increased? Even if that were the case, would these wars reach the scale of war-making attained by the industrialized nation-states of the 20th century?
