It would be nice now that the Cold War is over if we could totally eliminate our defense establishment with the knowledge that no nation would ever commit aggression against its neighbor again. But that's not the way the world is.
Winston Churchill used to tell a parable about a zoo in which all the animals decided to disarm. They arranged `peace talks' to work out the details. The rhinoceros asked for a strict ban against the use of teeth in war. The stag and porcupine agreed, but the lion and tiger defended teeth as being honorable weapons. The bear, however wanted both teeth and horns to be banned, but suggested that all animals be allowed to give each other a good hug when they quarreled. This only served to offend all the other animals, and so they never could agree.
That's the kind of world we live in. And thus, through the centuries young men, and sometimes young women, have been sacrificed in the cause of one noble ideal after another. Some of these wars have been senseless and barbaric, to be sure. But others have been necessary. We honor the memory this day of those who have given their lives believing that they were making the world safer, freer and more humane.
