Another way to run this would be to have a period of time before launches are possible for people to negotiate, and then to not allow retracting nukes after that point. And I think next time I would make it so that the total of no-nukes would be greater than the total if only one side nuked, though I did like this time that people had the option of a creative solution that “nuked” a side but lead to higher EV for both parties than not nuking.
You also need to only permit people who took part in the negotiations to launch nukes. Otherwise newcomers could just nuke without anyone having a chance to establish a precommittment to retaliate against them.
