President Obama recently made a speech to graduates at the U.S. Coast Guard Academy, arguing that climate change is a national security issue. This is an argument that the Pentagon made in a report last year. Many others have been making it for over a decade.
I’ve often thought that progressives who care about climate change should make the connection to national security more often, in an attempt to appeal to the values of cultural conservatives — although there will of course be limits to the persuasiveness of such an appeal if conservatives perceive it as coming from liberals.
More generally, what President Obama might call “a whole host of”* progressive policies could be advocated on national security grounds. This casts a new light on several previous arguments that have appeared on this blog.
