I'm writing a Superman story for one of my writing classes. And Lex Luthor is looking to create super villains like Metallo and the Parasite in order to have a private stock of unstoppable terrorists. He's looking to goad and prod other countries into global war so he can profit from gun running and gain political favor in the resulting instability and chaos. So basically my question is, in the currently political landscape what kind of events would cause a global war? I know the Middle East is a huge hot spot but is there anything specific that could cause it? PS: Wasn't sure if this was a plot question or a research question.
