A major international incident (the head of state of one nation violating the airspace of another) that completely and utterly dwarfs whatever nonsense was going on with Snowden. I know it's hard for geeks here to understand, but Snowden just isn't that important.
Again: he wasn't even on the plane. And Morales apparently had no intention of putting him on there. He was just pissed off that no one trusted him about that.
