Peace
The game also links it as Peace Offer, Peace Offers.
From the game's encyclopedia
Wars can end in three types of Peace: Victory, Defeat, or White Peace.
At 100% War Score, the other side cannot refuse a Peace Offer and must accept Defeat.
The effects of Victory or Defeat depend entirely on the type of Casus Belli that was used to declare the war and its associated War Target.
