Oil

Oil comes from the remains of the dead. Neocons dig up the oil, regardless of who lives above it, and burn it in order to make money and kill the environment. Sometimes people don't want the Neocons to use the dead bodies they live above to destroy the environment. The Neocons make up lies about the people, usually involving WMD's, then they kill them all.

Later, they will use the corpses they created by killing all opposition to make more oil, which they will use to kill the environment a little bit more.
