President Bush says, regarding his National Guard service in Alabama:
There may be no evidence, but I did report; otherwise, I wouldn’t have been honorably discharged. In other words, you don’t just say “I did something” without there being verification. Military doesn’t work that way. I got an honorable discharge, and I did show up in Alabama.
This really simplifies the question. It’s not about the honorable discharge, or whether or not it was OK to miss some service as long as you got the OK from your CO, or any of that. It’s about whether or not he showed up in Alabama. This isn’t a matter of missing documentation, either; it’s about documents which show no service in Alabama in 1972.
