My 2-cents is we don't need to calculate, we only need to ask, "if millions of people are locked behind a wall, with worsening indications that they'll ever be let out, how many years would it take a faction of those people, born in that "prison" to eventually find a way to swarm the gates and kill everyone they could find outside those gates?

Unless one has lived in such a place as Gaza, or even has friends there, how can we judge what is rational from their point of view?

It's grisly to look at the Palestinian boys killing Israelis, sending photos to their parents of "killing Jews", but we have to keep in mind they don't live in our world. They're called sub-humans, but isn't that exactly how they view people who would trap them behind a wall and treat them like useless cattle?
