Ironic, isn't it?
Their "informal" leader is hung up somewhere in Syria because he didn't realize he needed an official passport.
Oh, it's much worse than just "not realizing" -- he purposely rejected the whole concept, wrote himself a "citizen of the world" document, and presumed that the countries he traveled through would embrace him for it.
It wasn't ignorance, it was arrogant leftist starry-eyed idealism -- which crash-landed into reality.
