Augustine was the first important Christian theologian to justify war. His writings are wise and they were flatly violated by Bush the Lame. The Christian saint found himself living in a time that appeared to be the fulfilling of their scriptures. The known world was virtually all Christianized or rapidly becoming that way and so the end times were assumed by most thinkers to be at hand. It was necessary to stabilize their god's kingdom on earth to make straight the way for the return of their king.
Silly hobbits!
