Peace talks

War can be ended not only by outnumbering occupied regions but also by peace talks. The chances of success of the peace talks depend on the military policies of both countries and diplomatic relations. If the peace talks are successful, the initiator country will immediately emerge from the war. All the occupied regions will remain under initiator's control, and the regions occupied by the enemy will remain under the enemy's control. If the country was the only participant or a leader of the conflict party, the war will end immediately. If the country was a secondary party to the conflict, the war will continue without it, and the country's abandoned allies will break alliances with them and will be dissatisfied.

Gameplay Tips
