National cultures can indeed be changed.

Germany is the poster child: from Lebensraum to marching/protesting for US BLM in a mere 70 years.

Enormous costs in blood and treasure however. Lets not speak of how every woman between 8 and 80 were treated oh-so-tenderly in East Germany by our Soviet army allies as the lines between east and west solidified. Exact same thing that is spurring outrage on this OP, one might note.

(The Morgenthau Plan not implemented at least.. yet. TBD. Those Huns are darned fortunate the Cold War erupted, just saying. A suspicious mind would look at the NS pipeline popping and wonder.)

Japan did much better, of course. Their invasion of China was awful, but the communists were much, much worse. Sticky wicket, that business. Jeebus. Civil wars are a nightmare. Civil war + communist wins? "Suck start a bullet", as the saying goes.

Regardless: Israel isn't going to commit to a long term rebuilding/re-education plan for the Gaza Strip with an aim towards eventual integration as an independent nation state with the full privileges and responsibilities as a member of the free world.

I'd love to know what their objectives are, what "our" objectives are, and what the end game/exit strategy looks like.

Summarily executing 10,000 a-holes (Yay!, unironically) and 50,000 civilians (emphatic "BOO!") + breeding another generation of extremely angry Palestinians isn't going to fix anything.

Whole area needs to be shut down. Arab states need to step up and take these people in. Not going to happen in our lifetimes, because many, many reasons.
