"War" movies and their effects on war

War movies in my opinion do not effect nations desicions to go to war. Movies are so because they provoke emotions in their viewers that are not provoked form everyday situations. In the future "war" movies may provoke nations to go to war with muckraking movies and personal attackes on the falures of governments that do not belong to you. Until then I see no difference in human behavior after watching a "pro-war" movie or an "anti-war" movie.
