I don't think they're going to stop beheading prisoners any time soon. Obviously what we are doing in Iraq is not getting the point across to the terrorists, so we haven't done enough. I have friends over there right now, and the last thing I want is for them to get killed, but I can't agree with taking away all their support and retreating. If we abandon Iraq, the terrorists have won a major victory.
I try to focus my anger on an individual basis, because when targeting an entire country or religion, how many innocents are you going to kill? Fatherless children often grow into determined enemies. These recent atrocities make it difficult to see through blind hatred, but remember that God punishes the wicked, so do not let yourself be counted among them.
