True I would be out of land. Though it does make for an interesting round.

It would just make me feel better to be able to retaliate.

If there is a refusal to attack someone bigger I see no reason that it cant work the other way as well.

My ally in primary got hit by 2 countries whose NW is 10 million more. In response I went to attack back but a message popped up saying that my forces refuse to attack a country that much bigger then my own. Any way there can be a lift on that if you/your ally get hit by someone that much larger?
