If you haven't been to Mudville to read his piece on Fallujah and the Media coverage be sure that you do. He concludes with this quote from John Stuart Mill:

"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
