In a famous movie on World War II, by Quentin Tarantino, 'Inglorious Bastards' this was a notable Mexican standoff-dialog "You got guns on us. You decide to shoot, we're dead. Up top, they got grenades. They drop them down here, you're dead. That's a Mexican Standoff, and that was not the deal. No trust, no deal." - Lt. Aldo Raine.
