To my question.

Netanyahu has been killing people with no means of defense.

What is President Biden's motivation to keep sending military aide to Israel while Netanyahu continues to do this?

I have a few guesses, but none of them on their own or together seems to justify the political or humanitarian costs:

1. Somehow it is in the geopolitical interest of the U.S. to do so
2. Israel would be destroyed without military aide ( but defensive weapons can still be sent )
3. The U.S. benefits from Israeli intelligence
4. Congressional republicans aligned with Christian Nationlists want to see Israel live out a Biblical prophesy and it would cost President Biden politically if he were to push a decrease in military aide - assuming he could.
5. President Biden might have lost Jewish American votes, BUT Jews are a minority in America and many American Jews are against what Netanyahu is doing.

Those are the possibilities I could come up with. Am I missing anything? All of these possibilities together do not seem to be worth the political cost President Biden incurred. Is there something I missed?
