(1) You cannot concretely describe how Israel could wage war in a more humanitarian manner, because Israel already is waging war in as humanitarian a way as possible. And (2) America & the USSR killed half of all German & Japanese men in WWII and carpet bombed cities, but after WWII Germans & Japanese didn't engage in terrorism. Whether Palestinians choose to continue engaging in terrorism into the future is 100% the result of their freewill decisions; terrorism is not an understandable result of civilian casualties as you falsely claim.
