How should we respond to the latest Middle East crises?

It's a genuine question and I don't have an answer. Today I played a squash league match against Sam (I lost again and should have won - doh). Sam is a young Jewish guy who I've talked to before about faith and Judaism. He's a nice guy, although I didn't like his lack of compassion towards the innocent civilians in Lebanon (it's Hezbollah's fault for using human sandbags). Thanks Andrew for this article which presents a different view and links to Christians in the Lebanon, who at least I can pray for, although I would like to do more.
