Jesus, Lord of War.

From the Raw Story:

"DENVER — In a town in scenic southwestern Colorado, homeowners are battling over whether a Christmas wreath that includes a peace sign is an anti-Iraq war protest or a promotion of Satan...

"Kearns... said he was concerned about the pagan symbolism of the peace sign. 'It’s also an anti-Christ sign. That’s how it started,' he told the Durango Herald."

We assume this explains Satan's popular designation as the Prince of Peace.
