Well, there was a little event we call 9-11 between Clintoon and W, so it's hard to compare anything between the two, except to say that the Clintons helped bring on the attack.
As for the CinC influencing who enlists and when, I don't know? I enlisted during the JFK years and one of my sons enlisted late in the W41 years. I don't believe their politics influenced either of us. It was relatively peaceful in 61 and 92, put for those enlisting in the late 60s or after 9-11 - the world changed a bit.
We are a military family and I can tell you that I know plenty of former military that just would not serve under Clinton.
