Thirty Seconds to Mars
released their third album This Is War
in 2009 and are just now putting out a music video for a track from that album of the same name. At the beginning of the video for "This Is War" there is a disclosure that this is a song about peace. The video would suggest otherwise for it deals with imagery of politics and war form all around the world and during different epochs by posing juxtapositions of good vs. bad. It gets pretty ridiculous halfway through as lead singer Jared Leto, dressed in fatigues, shoots at military tanks falling from the sky. Still, it's pretty clear that they have anti-war/pro-peace sentiments.
