Yeah it's not a bad video idea.
If someone was to see the video about war and soldires, then read the lyrics, I think it would easily be interpreted as a song about war, because it does make sence. Personal interpretation is the main key.
Good point about the Higher video, by the way. I think music videos are an easy way of confusing what the song is actually about. This is just off the top of my head but take a easily read music video, like Jeremy by Pearl Jam. If someone was to watch and hear that song for the first time you would easily know what it was about, beacuse you see it happening in the video. Where as a confusing and weird video like Bullets by Creed for example, they wouldn't know what it's about and probably think it's about some cartoon that involves monsters with huge angel wings flying around.
My point is, some music videos are confusing.
Just my opinion, hah.
