any iteration you can't perform the tit-for-tat strategy.

What you say is substantiated by the descriptions in the book.
But what I was talking about is that you can't be massively outgunned. It's

to require that the entities cooperating be similar in strength and
capacity to do harm--at least within the model as described. Sharks have
little reason to cooperate with halibut.

This is one of the hidden (or at least unpiblicized) costs of term limits.
It increases the "lame duck" period when elected officials can't be sure
their logrolling will pay off. "Why should I cut a deal with Senator X,
