"... a candidate for peace who would act swiftly to end the wars in the Middle East and beyond..."
They never bothered to tell them -how- he would be ending those wars. I guess sometimes the peaceful solution is a bloody one. Peaceful as in there's nobody left to fight back.
For instrumental music with no vocals, try: Wide Eyes, Invent Animate (their instrumental versions), Modern Day Babylon, I Built the Sky. These aren't quite Death Metal, but they have really complex guitar and drum pieces.
For with vocals: Sea in the Sky, Ignea, Unleash The Archers, Corelia (also has instrumental version of their 1 album)
