Jules Crittenden gives a good lesson on "Good" wars versus "Bad" wars this morning. I highly recommend checking it out:
Many, many years ago, nobody believed anyone could be quite so suicidally crazy as they turned out to be. And after they attacked our nation, negotiating with suicidal madmen who wanted to take over the world was considered an absurd idea. People would have looked at you like you were a madman if you suggested it. It was a simpler time. It was a Good War, and it was long, long ago. The suicidal madmen were killed instead, in large numbers. Many of ours died doing this. Finally, after many of the suicidal madmen had been killed, and the remaining ones still refused to consider surrender, it was necessary to drop two nuclear bombs, killing several hundred thousand people in order to prevent the deaths of millions more in an invasion. It was very bad, even though the war was good.
