I think Israel is expecting to be told “no” eventually, but to never have to make recompense for their actions or return the land, so they might as well just keep pushing until the United States eventually can’t tolerate any more. That point should have been in the past, but even establishment Zionists will eventually hit their limit.
Since whatever consequences they’ll face will probably just be a “stop” and at most some token reparations or rights for Palestinians, and the amount of their wrongdoing generally doesn’t impact the size of the consequences, might as well pack in land theft and ethnic cleansing in the West Bank along with the genocide. Then they’ll go through a few more years of slower colonialism before finding another provocation to allow them to once again go fast.
