The LA Times interviews George Shultz about oil, climate change, and Prop. 23:
Former U.S. secretary of State George P. Shultz believes it's crucial to fight global warming to protect national security.
Global warming is created by burning fossil fuel, he says, and payments for foreign oil sometimes wind up financing terrorism.
And Shultz, who's also a former Treasury secretary, thinks the nation suffers an "economic vulnerability" because of its oil addiction.
