Mike Morgan of Los Osos writes that bumper stickers advocating peace will not save us from war, that they are just the cries of a bunch of “nuts” who know no better.

Mike, meet one of those nuts. I have a little sign propped in the rear window of my car that says “WAR IS NOT THE ANSWER.” You say technology is without saying how the techies will bring about peace. If they can do it, more power to them. Meanwhile I’ll stick with my sign, although it does not explain what the answer is, either. At the very least, it can help me find my car in a crowded parking lot.

For a more detailed explanation, I might recommend “Washington Rules,” by Andrew Bacevich, a retired U.S. Army colonel. Why does a career soldier advocate peace and explain how to make it happen? It’s understandable when you learn that he lost a son, who was killed in Afghanistan while trying to follow in Dad’s footsteps.
