John Renehan joined the military and confused some of his friends. An excerpt from the City Journal article:
No, at the end of the day, the issue was simply that I had joined the military. And that act was just too foreign for some in my old circles to recognize as having arisen from the normal range of motivations—chosen as one might choose to go back to school, or perform charity work, or embark on any other course that might prove rewarding. In their cosmopolitan world—my former and sometime world—wartime stints in the military just aren’t done. Not when one has other options—which everyone in that world always has.
