This might sound weird, but whenever I think of this song I relate it to 9/11. "The blood of innocence burning in the skies" being all the innocent people who died in the plane and in the buildings. "Poured it out in an ocean of debris." Being all the debris from the buildings falling. "Swimming in the smoke" being all the smoke from the buildings. "We held our breathe when the clouds began to form. But you were lost in the beating of the storm. and in the end we were made to be apart." Being when the towers were hit or fell and the person he is talking about died in the crash. For him saying the blame his alone he could be talking about all the sins him or the nation as a whole we have commited and now bad is happening to us/him. Just how I see it.
