The Christian Science Monitor has an interesting and, I think, well balanced article on plans of some Christians agencies to evangelize as they offer aid in Iraq, possible effects of that and generally the balance of right to express one's religious beliefs by evangelizing and that of being free from intrusion.

(BTW, a few years ago, when my kid brother left for diplomatic post in Iran I took care about letting his house; the tennant was a Southern Baptist missionary with family: most friendly folks!)
