Worldwide, we're seeing electorates that are rejecting establishment candidates. It's been that way since at least 2016, and really since the start of and response to the Great Recession. Obama ran as an outsider. He governed as a centrist, but he didn't really run as one initially. And Biden only won because of the pandemic. If it weren't for the pandemic, Trump would have won in 2020.

Obama campaigned on a platform of change. He promised healthcare and (very importantly at that time) to pull troops from Iraq/Afghanistan. His campaign was very aspirational, even if his first term in office was not. That campaign won in Indiana and Ohio, to give an idea of the popularity of these ideas. Biden won by a very small nr of voters in the swing states running against a (at that time) very unpopular president.

I'm not claiming things I have no evidence for. The Biden administration has repeatedly and explicitly refused to make any US aid to Israel contingent on any improvement on the situation in Gaza.

The Biden administration has openly refused calls to use US aid as leverage against Israel, and all you can do is wave your hands and say, "hrr, umm, actually, you can't know what went on behind the scenes, so maybe Biden did do that, but we just have no evidence of that."

You are asking me to prove a negative. You are demanding that I prove that Biden HASN'T secretly used US leverage to rein in Israel. That is not how this works. If you want to claim that the US actually has tried to put the screws on Israel, YOU need to produce some evidence of that claim. So far, a least according to everything publicly available from all sources, Biden has given Israel a complete blank check. If you want to claim something contrary to all evidence, then you need to supply that evidence.

After all, it's also possible that the Gazans aren't being killed by Israel at all. Maybe the Martians are just coming and abducting all the Palestinians to Mars. And we don't see the Martians, because they're invisible. You have no evidence that there AREN'T Martians killing all the Gazans, so I guess it would be foolish to write off the idea.

The problem with it is that it was more or less the same thing Biden said and it's been abundantly clear Biden does not care for a ceasefire. The Arabs wanted more than that. They wanted her to admit that what Israel was doing in Gaza and Lebanon was wrong. They wanted her to say that she would take a firmer stance than Biden would on Israel. They didnt want her to say that she supports Israels right to defend itself, or for Tim Walz to say he supports Israels right to expand its borders, or even to campaign with Liz Cheney. The icing on the cake was Bill Clintons very stupid attempt to justify Israels killing of civilians a day or two before the election. What she said clearly wasn't enough and she repeatedly ignored them as well as the DNC actively trying to silence them.

I believe she did end up taking a slightly firmer stance a few days before the election, which is likely due to her not polling so well. I'm not sure if your quote is from that time or from before. But I think a lot of Arabs saw it as "too little, too late" kind of thing.

which is still and order from her boss

This is complete nonsense. The vice president isn't duty bound to never contradict the president, especially when running to succeed him. When a boss orders you to do something that's wrong, you can say no, particularly when you don't need the job anymore and are already applying for a better one.

Harris didn't say more on Gaza because she didn't want to, whether due to personal beliefs or because she for some reason thought it was a better electoral stance, not because of all-powerful orders from Joe Biden.

What of those are actually new policies? Has Biden ever come out in favor of Israel annexing the West Bank, or in favor of forced displacement? Of course not. They're liberals, not Republicans. Centrist liberals like Biden and Harris want to talk, but that's all they want to do. There is nothing you cited there that hasn't been happily endorsed by liberals for decades, all while Israel tightens the screws on the Palestinians ever-tighter.

It's all meaningless words and platitudes. While she's SAID things that would be great to do, she has refused to actually use US leverage to DO any of those things. The Biden administration also talks about endorsing a two-state solution and all the things you mention. Again, Biden talks in fluffy glittering generalities when it comes to saving the Gazan people, but he refuses to actually back those words with actions.

What precisely, did Harris propose to actually achieve any of those things she's laid out? What leverage would she use to force Israel to accept these?
