As a veteran, I find that the facileness with which that is said way too many times to be without any true meaning.  It's like:  How are you today?  Fine.  Have a nice day.

btw, I think that the 8 years of military service that I had was one of THE best experiences of my life.  I with that this country had a mandatory service requirement (military or civilian) for ALL individuals with few if any exemptions allowed.  I think we'd have a lot less war-mongering and appreciation for these the least of our brethren if everyone had to have that exposure to that which was not familiar to them
