Not sure if this has been suggested or not, but it would be a cool feature of the Diplomacy Card to add neutrals to the list. What this would do would hinder your opponent so that they couldn't expand for a certain amount of turns. This could turn the tide for the losing end and get them back in the game.

Thoughts?

I also made a UserVoice item for this one so please vote!:
