As it stands Israel had to accept a ceasefire process for Gaza, which is pracitcally identical to what was proposed almost a year ago, but Biden didnt apply any pressure. It increased the rifts inside Israels society and parts of the current government coalition left.

That is a huge defeat for the Israeli government and they wouldnt have accepted it, if there wasnt tangible pressure behing it, e.g. the US cutting off the Arms and Money. Also Biden made a point of quickly passing another few billions to Israel iirc. in November or December, so he also must have feared them to run dry under Trump.

Most political analysts say that Trump believes in zero sum deals. Israel is a strategic, financial and diplomatic liability to the US. If it is about having a military base in the region Trump could easily strike a deal with another country around.

Also looking at what typical MAGA heads like Tucker Carlson say, the sentiment towards Israel among the Republicans has changed. More people ask the question, why they should pay up for Israels bullshit. When “The backing of the most powerful military” in practice becomes Videos of American kids being killed, so Israelis can enjoy watching from the beach-side café how the US is expanding their empire, the mood will turn sour quickly.
