She's banking that Trump will cut foreign aid to Israel, and then sit back and do nothing when the Second Holocaust goes "from the river to the sea."
She's probably right that Trump would let it happen, but she's vastly overestimating the competence of her own people. Big blindspot from her.
I doubt Trump gives much thought to his policies beyond the first action he would take, but I wouldn't be surprised if some in that post-alt-right sphere would have the US divest from Israel specifically so Netanyahu would align with Russia and form a far-right Judeo-Christian axis coalition at the Eurasian crossroads without the US needing to spend any money on either.
Why would Israel or Russia want that? Even if there was a slight chance in the past, Putin's response to 10/7 ruined any opportunity as long as the war continues. Russia's main allies include Iran & Syria who want to see Israel wiped off the map. The only way I could see Israel & Russia form an alliance is if the west completely turns its back on Israel and its adversaries moderate their stance. The former I can see happening, the later would require regime change.
Russia isn't aligned with Syria and Iran because it believes in Baathism or Shi'a theocracy. It's allied with Syria because Syria lets them have a naval and air base in the Mediterranean, and Iran because it sells them drones on the cheap, hates the US, and helps them to keep Assad in power. If someone else were to make them a similar offer, there's nothing inherently tying Russia to either country. Meanwhile, something like 20% of Israel's population is of post-Soviet extraction.
Not saying it's going to happen, and I obviously don't want it to happen, just that if you're on the fringe right, I can see it being a pie in the sky idea.
