Further to the comments on secularism below, and for anyone interested in the mindset of some of the American troops currently "liberating" Fallujah, a little noticed report from Agence France Presse makes pretty hair-raising reading:

Marines turn to God ahead of anticipated Fallujah battle

With US forces massing outside Fallujah, 35 marines swayed to Christian rock music and asked Jesus Christ to protect them in what could be the biggest battle since American troops invaded Iraq last year...

"You are the sovereign. Your name is holy. You are the pure spotless lamb," a female voice cried out on the loudspeakers as the marines clapped their hands and closed their eyes, reflecting on what lay ahead for them...

One spoke of their Old Testament hero, a shepherd who would become Israel's king, battling the Philistines some 3,000 years ago. "Thus David prevailed over the Philistines," the marine said... and the marines shouted back "Hoorah, King David," using their signature grunt of approval.

Check the weirdo Christian Zionist undercurrent to the King David stuff. The reporter also makes this connection, noting how the marines "perceive themselves as warriors fighting barbaric men opposed to all that is good in the world".
