You realize that you're currently being con'd. Netanyahu wants Trump to win the presidential election, because he knows Trump will be friendly towards his genocidal actions. Netanyahu is doing everything in his power to extend this genocide so that he can stay in power; and so that he can keep single issue voters like you away from the polls.
Netanyahu knows that if he ended Israel's genocide before the election, the Biden administration would receive credit in playing a role in mediating the conflict. This would likely assure a Harris victory. By escalating the conflct, he is assisting Trump. Why would you think that this genocidal maniac is doing this?
So here you are, the single issue voter that is tuning out all of the other important issues. For example, Trump considers communist (all you genius tankies) some of the biggest enemies in the USA; or how Trump backers and policymakers wants to remove women's right to make decisions about their bodies.
Do I believe that Biden/Harris has done enough to help Palestinians? The answer is no. Do I believe Biden/Harris feels like Netanyahu and the Israeli government are in the wrong? Yes. Do I believe Trump feels like Israel is in the wrong? No.
So even if this is your single issue, as an American living thousands of miles from Israel, your best way to assist Palestinians right now is to put someone in the Whitehouse who at least views them as human-beings. By not voting or voting third-party, you're not helping anyone but yourself. You are doing it so you don't need to "feel bad" about crossing some morale boundary.
Listen man, if that's the route you want to go, then fine. But I'm gonna go ahead and waltz my sorry butt to the polls and cast my vote for the person who will more likely do something to assist Palestinians even if I feel like I'm crossing a moral boundary. Am I gonna feel good doing it? No. But it's the better decision to make, especially considering all the other important issues that surround this election beyond the Palestinian genocide.
