Nothing really, it’s a lose-lose.

In terms of geopolitical strategy, Turkey could serve the same kind of function as Israel in terms of aiding the US in projecting regional influence.

And then morally, obviously, there is no case to be made for supporting Israel.

I guess the only real consideration is that Israel has nukes, but then so does North Korea, China, Russia etc.

This is purely ideological for Biden. If it was strategic his staffers likely wouldn’t be resigning, but they recognize that this is a product of fantacism.
