In the light of civilian casualties, how do you perceive the principle of proportionality as applied to the Israeli military operations in Gaza?

I believe that America should cut off Israel and be on the side of the Palestinian people who are being genocided in the space of the Gaza Strip, an open-air prison. Israel is actively cleansing the land of its people, a defenseless people with a huge population of children - where their life expectancy is 18.

I agree that Israel should refrain from extreme military retaliation against Hamas that will jeopardize either Israeli or Palestinian civilians. I also believe that Israel is partially to blame for the "surprise" attack by Hamas. When people are pushed into a corner, of course they will fight back. I don't think Hamas is right in targeting civilians or even using military force, but Israel is not innocent.
