A controversial move was made in the world of comics this week with Superman, of all people, threatening to give up his American citizenship.

The Los Angeles Times reported that in the latest issue of Action Comics, Clark Kent's alter ego decides he's had enough, after the Secret Service reprimands the superhero for appearing at a non-violent protest against the Iranian government.

"I intend to speak before the United Nations tomorrow and inform them that I am renouncing my U.S. citizenship," the Man of Steel says. "I'm tired of having my actions construed as instruments of U.S. policy."

He also indicates that his famous motto is too narrow: "'Truth, justice and the American way' -- it's not enough anymore," he explains. "The world is too small, too connected."

It's often assumed Superman is American, having been raised by adoptive parents in Kansas. But he was born on the fictional planet Krypton, so his citizenship could technically have always been up for grabs. Still, many are unhappy with the mere threat. A Weekly Standard blogger called this latest development the dumbest thing DC Comics could do: "What does 'citizen of the Universe' even mean?"
