Imagine for a minute that the Chinese have developed a new weapon that does hundreds of billions of dollars of damage to our country every year. How would the GOP react? Do you think they would dismiss the idea of spending huge amounts of public money to respond to this threat? Of course not.
If the same amount of damage is attributable to climate change, however, it is perfectly OK to dismiss the threat as a plot by left-wingers to increase the size of government. Growing the state therefore can be acceptable, but only if it involves increases to defense spending, because the GOP is all about kicking butt, not protecting our citizens.
