My answer would be don't waste your time and energy.
We have 6 inch chimp brains. Some types of problems require 7 inch chimp brains or 2000 inch chimp brains or 7 million inch chimp brains.
The only thing you have to understand when you take 2 chimps and throw them into a room with such type of complex problems is blundering ensues.
The focus of all chimps is then drawn to the blundering, whose fault it is, who said what, who did what, who can be blamed, who needs to change etc etc etc but all that just takes focus away from the fact that the problem itself is too complex for a chimp.
This is the Theory of Bounded Rationality (which won a Nobel Prize for explaining why the world couldnt prevent world war 2 after experiencing the devastation of world war 1).
Not everything can be understood. Misunderstanding on the other hand is directly proportional to the complexity of the problem. And it doesn't get more complex that the Israel-Palestine issue.
The chimps will continue to blunder.
The Theory of Bounded Rationality recommends teaching kids that are facing complex problems to ditch them and instead work on simple ones.
