Maybe you should reconsider your prejudice, then. Why are you so spiteful towards the country geopolitically opposed to the genocidal entity and doing something about it? Do you treat western countries (all of them maintaining economic, diplomatic and military ties with Israel) with the same contempt?

I personally prefer the more complex setup discussed in https://ncase.me/trust/.

The prisoners dilemma is a single decision game: you can tattle or stay silent, and as you don't know what the other does, and due to how things are set up you would prefer to tattle, even if both staying silent yields better results for both parties.

Politics like this is more of a repeated game, like the one described in the link. You can trust one another, in spite of this single iteration Pareto optimal setting favoring betrayal, and work together. But also; show that you are not an easy mark that can be exploited.
