I wanted to respond to each part separately but realized the sheer stupidity of what you're trying to argue here is refutation of itself enough on its own.
The bolded part is not something anyone here argued.
Hamas did not engineer the battlefield. They're incapable of engineering any battlefield given the asymmetrical nature of this conflict. You continue to treat Gaza as if it's a huge swat of land. It's not, yet you continue to ignore that repeatedly. The reason people put most of the blame on Israel is because Israel has the most power to dictate what's happening in Gaza. Israel decided on the borders of Gaza. Israel decided on keeping over a million Palestinian refugees in Gaza. Israel decided to hold Gaza under siege for decades depriving the locals of a basic livelihood. Israel decided to bar the Palestinian Authority from exerting any civilian control on Gaza. Hamas engineered none of that.
