I would agree with the provision that it only applies during the one game. New game, new teams, new situation. When it's apparent that you're on the outer of a 3 man alliance, and your only hope for an ally desperately wants to keep a tech away from that alliance, desperate moves are made that normally wouldn't be considered. Especially when the only potential ally is actually working with you, and is constantly in contact with you.
Once a backstabber always a backstabber...once a deal braker always a deal braker.
Personaly I would never trust again someone who broke a deal in any future game.
