It's Pretty Obvious This Is A Battle, But Who Is It That's Fighting?

*ALERT* UFOs OVER SAKURAJIMA JAPAN! *ALERT*  Awesome video narrated by BeePee Oil Disaster(Who, evidently, is a lover of the weed..) showing some kind of battle, but it's not clear who or what is fighting who or what.  But something is happening.  Watch the video.  I honestly don't know what to think.  Is this alien, or scalar warfare?
