What is the theme in Idiot's Delight by Robert E. Sherwood?

Fatalism is a theme. The characters in this play all know that war is coming and that it will affect their lives. At first, they each come onto the stage expressing their urgent need to get out of the war zone before the fighting begins. When it has been confirmed that bombs have been dropped on Paris, though, they all realize that their lives are going to be subject to circumstances beyond their control.
