I don’t think it’s a ridiculous question, I think it’s a difficult and uncomfortable one that you don’t even want to begin to answer.
Yes, a tally should be kept, and this tally should be used when considering whether the response has been proportionate.
Yes their is a price, the people in Gaza who are being murdered, the people in the West Bank who are being harassed, the people in Israel sent to fight, and the people who have left their homes on the borders of Israel, are paying the price. Everyone who has to live with the economic fall out and the damage done to the reputation of Israel will pay the price.
The Israeli who died in the hostage operation, and their family, paid the price.
The costs are too high and the benefits are too low. I believe there will be no peace for Israel without peace for Palestine, and while Israel is attacking Gaza, there is no peace.
