Just a distraction.

I mean the easiest way of overthrowing Netanyahu would be for the US to stop giving Israel money while he's in power. He'd be gone by lunchtime.

Israel would be gone by lunch time.

No, as a thought experiment, I think if regime change meant continued US support they'd be safe from neighbouring countries while negotiating that change.

Given the "enemy" they are bombarding lacks the capacity to retaliate at scale no real harm would come to them if they had to just stop genociding and occupying.

They would have to concentrate their resources on defence in the normal sense of the word.

Israel isn’t afraid of Hamas if US drops support, they’re afraid of Iran and several other Arabic countries. Palestine is just testing/training grounds for their military in their own eyes.
