How is my regions state of war related to my Defcon Levels?
DEFCON Levels can only be changed within certain parameters. When actively at War with another region you are automatically at DEFCON Level 3 or higher (War sets your DEFCON to 3 automatically — you would have to manually increase this to Level 2 or Level 1 if you wanted the further improvements.) Signing a Ceasefire agreement will allow you to reduce your DEFCON to Level 4 should you so decide. You must at least be “Neutral” with all regions to stay at DEFCON 5. Similarly, if you are neutral with all other regions you can only elevate your DEFCON as high as Level 2 and NOT to Level 1. –> For more details see the game manual pages 53, 54.
