No, actually. It was the part about someone killing your whole family, while everyone else sits back and just watches it happen, sometimes with approval. That's basically what the world has been doing while Israel kills hundreds of thousands of people.

It was also the trolley problem metaphor itself, in the next paragraph. The rest of the world could stop the genocide, by simply cutting Israel off. No more weapons, means no more killing. But it would also leave Israel defenseless.

So, should the world pull the lever and save Gaza, knowing it will ultimately lead to more Israelis dying? Or should they keep giving them more weapons, so that they can keep murdering Palestinians with them?

This is the "leverage" Netanyahu uses to coerce the world into looking the other way, while he keeps killing more children.
