I would add - the situation isn’t going to change. I’ve met a lot of young Republicans over the past couple of years in their 20s through a college group one of my daughters belonged to, and the majority I talked to made it clear they had no intention of serving (even as officers, being that they had their degrees or would be completing them within a few years). A few said they were considering it, because it would look good on their resume or if they ran for office later on. Slightly disconcerting, and I’ve heard similar stories from friends elsewhere, but it makes me appreciate those who do serve all the more.
Those young men sound like a good number of the radio ‘conservatives’ offered to us these days. Few if any served, and some actively sought to get out of serving. Some were antiwar protestors during Vietnam.
