That is, I think, an excellent and pertinent question.
For starters may I suggest applying straightforward quantification on a linear scale and observing the results? See the following two wiki articles / subsections:
1. https://en.wikipedia.org/wiki/Israeli%E2%80%93Palestinian_co... (see chart preceding the Gaza war (follow anchor))
2. https://en.wikipedia.org/wiki/Casualties_of_the_Gaza_war (Gaza war; see top table (and subsequent charts for more detailed breakdown if interested))
Based on this quantitative data where would you place Israel on that aforementioned scale?
