M.I.A song meaning

Johnny Christ on the song's meaning: "The impact of the MIA thing was that we have a lot of friends of ours that have gone to Iraq. Some of them have come back and some of them haven't. The ones that have come back, we get our chance to hang out with them. They tell some pretty crazy stories of what they have seen, because a lot of our friends have been in the front line. We just kind of wrote about their experiences, of what has gone on there. It is not so much a political song, it is just about the stories we have heard from our friends."
