My friend and I are playing the Byzantine Emperor and the King of Anatolia, Syria, and Armenia, respectively. For the last 30 years I've been making sure that the Mongols only have a regency and I've married into the golden horde. My question is this, can I wage war on the Ilkhanate, press surrender and have 10 years of peace so I can expand south westward towards west Africa and my friend absorbing the HRE/Bohemia? Because we really need the time to martial resources to fight off his 200+K horse archers and at the moment we would just...die.
