The Swift Boating of John Kerry

Let's look at the intent of the so-called Swift Boat Veteran's. Their purpose WAS NOT to refute his testimony about the Vietnam War, but to DESTROY A HUMAN.
Very few wars have been fought without atrocities being committed by both sides. It's the nature of war. I'm not trying to justify it, but pointing out a fact.
Have you ever heard anyone use the expression "a fair fight", or "fight fair"? If you or I engage anyone in a fight, isn't our objective to win, and by using any means at our disposal?
To a lesser extent, and most especially in Vietnam, we didn't know at times who we were fighting, and did what we had to do. I don't think Kerry was wrong by pointing this out, and that the SBVT's were wrong in trying to suppress the truth, and vilifying and attempting to destroy the messenger.
Are we not mature enough to acknowledge that when it comes to warfare, we're no different than anyone else in our desire for survival.
Of course these are war crimes just as sure as the treatment of prisoners at Abu Garib was.
We did what we had to do.
Wars are futile, and in the long run do not solve anything. Isn't this what the man we call "The Prince of Peace" was trying to teach? It is a lesson that so many of us that claim to follow his teachings still have to learn.
On this July Fourth, the anniversary of our independence, shouldn't we be turning our eyes toward the goal of freedom and indepencence for all people?
