I don’t think Korea should be relevant to the American future because permanent foreign deployments should be a thing of the past now that the special case of the Cold War ended. Our nation never lost soldiers in early war overseas battles til we started electing progressive self-appointed world messiahs like Wilson, FDR, and LBJ.
“Should be a thing of the past” is far from reality. You want to bet your child’s/grandchild’s life on that?
