Me watching it has nothing to do with my questions above. Please read them properly.
Unless what you propose is that hamas watched that video, got back in time with the knowledge that "this time Israel will do such a thing" and attacked...
I think calling that demonstration peaceful is at least a simplification but let's forget that.
"Asking less nicely" you say. But I don't see proofs of that really being the purpose of hamas actions. Asking in a way that would not lead to further deaths of your own people should have been the way.
Yet they were building rockets instead of defenses all this time. If they couldnt eradicate all that they needed/wanted (the whole Israel I guess) why even start something like the October 7 attack?
