The word was "credibility". It's very easy to wage war with someone else's kids.
I don't subscribe to the idea that one must be in the military to support the war, any more than I believe everyone in the military automatically supports the war. (Obeying orders is not the same thing.) I have noticed the part of the population that has the most young people enlisting, though.

Bill Clinton's military record was far from buried during his administration. A Republican brought it up every other week.
