National Peace/War Preference - The Peace/War Preference option allows you to specify whether or not you want to allow other nations to declare war on you and attack your nation or to play the game as a peaceful nation. Keeping your nation in peace mode for prolonged periods of time will damage your nations economy. New nations get a 7 day grace period when in peace mode to allow them to learn the game without receiving any economic penalties. If your nation is older than 7 days and you remain in peace mode for more than:
4 days = -3 population happiness
6 days = -5 population happiness
8 days = -6 population happiness
10 days = -7 population happiness
12 days = -8 population happiness
14 days = -9 population happiness
There is also an additional economic penalty on top of the population happiness penalty if your nation is in peace mode for more than 5 days. A nation in peace mode may not send foreign aid, however it will be allowed to continue to receive foreign aid. In order to exit peace mode nations are required to collect taxes on the day that they wish to change out of peace mode.
