Are you under the impression Israel is stopping?
I thought you believed this has been going on for 75 years?
Why don't you believe Trump and the Republicans when they say they think Biden is too soft in his support of Israel?
Why don't you believe the Israeli government when they say Biden isn't supportive enough and Trump will be better?
Even if you think Trump will suddenly abandon Bibi, why do you think the party that is actively campaigning on being more strongly pro-Israel and anti-Palestenian winning the election will be a signal to the US government that it should stop being so pro-Israel?
Israel will stop the genocide, yes, but of course they won't stop the settler colonialism until outside pressure forces them.
2021, 2018, 2014, 2012, 2011, IIRC, all those attacks on Gaza stopped eventually. The longest being the Great March of Return, but that was only a weekly protest that lasted nearly a year. About 200 died and 14,000 or so injured, but it wasn't near what this was. This one is by far the most serious and deadly, and its only because Netanyahu is pressured and Biden is allowing it to happen. Previously Netanyahu knew when to stop before global outrage was too much, as when the 2021 protests became a PLM movement.
All Israeli attacks eventually stop.
The bigger problem is how to end the Negroponte doctrine and allow the UN, ICC and ICJ to finally take place and even more importantly, for the grassroots support for BDS to do what it did to South African Apartheid.
Will Netanyahu still be in power to try another attack in the next 4 years with an orange POTUS? That's unclear. He's incredibly unpopular but Netanyahu has survived other political challenges. Would he try this again? Unlikely. If he did would rump back him, probably. But will rump live through another 4 years in office? Also unlikely.
Will the dems change if Biden loses? Very likely. The wave against AIPAC is real and losing will look massive.
Your option is to put Biden back in, watch him protect Netanyahu as the ICC and ICJ try to rule and the US vetos those actions and blocks all UNSC resolutions, allowing the issue fester in the background for another 4 years until Ben Gvir or whoever leads next tries something much worse.
Do you really see that as better?
Do you have an alternate storyline that looks more plausible and has a better outcome?
