Simple? Voltaire warned us, "beware of the great simplifiers".
Gaza has been unoccupied since 2005. Gazans voted for Hamas in 2006. Hamas then took absolute power in a bloody coup and civil war against Fatah in 2007, throwing Fatah police off rooftops. The Palestinian statelet then became a failed state before it was a sovereign state, with Hamas' billionaire leaders living in luxury in Doha while indoctrinating children to be terrorists: https://www.youtube.com/watch?v=vCWMBvxWKL0.
The blockade is a joint Egyptian-Israeli blockade.
The Geneva Convention's clause about proportionality gives legal force to intentionality. Read clause IV:
"Intentionally launching an attack in the knowledge that such attack will cause incidental loss of life or injury to civilians or damage to civilian objects or widespread, long-term and severe damage to the natural environment which would be clearly excessive in relation to the concrete and direct overall military advantage anticipated;"
If you fire an RPG from a hospital window, that hospital loses its protected status. Every Israeli unit has a legal advisor telling those selecting targets what they can and cannot fire on.
Israel has made 30000 phone calls to Gazans warning them of targeting decisions in advance, allowing both Hamas and civilians to escape. Here's just one example: https://www.msn.com/en-us/news/world/israeli-intelligence-spent-hours-on-phone-with-gaza-dentist-coached-him-through-apartment-evacuation-to-avoid-civilian-casualties/ar-AA1jBXkL
No military in history has ever gone to such lengths to minimize civilian casualties, to the detriment of its own military objectives.
If you see no difference between the IDF soldier on the phone with the dentist and this behavior by Hamas terrorists:
"Hamas Terrorists Gang-Raped Israeli Woman Before One of the Rapists Shot Her in the Head While He Was Still Having Sex with Her: Report
According to Haaretz, the witness recounted the harrowing attack, describing how she saw it unfold while hiding from Hamas gunmen dressed in military uniforms.
Hamas terrorists gang-raped an Israeli woman before one of them shot her in the back of the head while he was still having sex with her, according to witness testimony. Lahav 433, an umbrella organization dedicated to combating crime and dubbed the "Israeli FBI," has been collecting evidence of sexual assaults during the attack that took place on October 7."
You've completely detached morality from intentions and live in a foreign moral universe.
Using the term "concentration camp" and other Holocaust terminology is deliberate and anti-semitic Jew taunting designed to wound.
All 5500 children would be alive if Hamas hadn't started the war using them as human shields, which is explicit Hamas policy: https://www.youtube.com/watch?v=UXZEzbT0H1s
should you bother to listen to Hamas itself and take them at their word, which I do.
