Shouldn't the entente players get to recognize war aims as well as the CPs? I swear in WW1 there were more options for this.
The Allies did give Italy, Romania and Greece recognition of some or all of their goals. Honestly, every WW1 game ever made assumes the Bulgarians are CP but historically there was a strong lobby for joining Russia and disliking the Ottomans and there were discussions in the British parliament of recognizing more Bulgarian goals.
