In the Name of Religion
I think it's human nature to seek retribution. Hiding behind a religion makes it that much worse, not justifiable.
Time and again military leaders describe their actions with references to Islam or Christianity. Neither religion approves of the hatred towards your enemies. In fact both practice forgiveness.
You want to wage war against your enemies, fine. But don't hide behind your religion when it advocates a peaceful solution. Religion isn't even what this is about. Referring to "your god" will only polarize the issue.
