They will take money and weapons from other nations who want their influence in the middle east and the only thing that will change is the US losing that influence.
If the US stops supporting Israel, which other nation will step in and send them 1500lb bombs, highly advanced targeting systems, tens of thousands of artillery shells (theres a worldwide shortage), propelling charges for howitzers, hellfire missiles, disposable shoulder fired rockets, and a plethora of small arms? Be specific.
There are only 4 or 5 nations with the ability to supply the weaponry that Israel needs. China and Russia have been opposed to the genocide since the beginning, so unless they take a dramatic self-destructive turn, this only leaves western nations. Do you think Germany, Japan, or South Korea would defy the US in order to support Israel?
That phone call already happened. It was international news.
Can you provide a source for this?
The only story I'm aware of is how Biden's aides have been leaking how hes having confrontational phone calls with Netanyahu. This is obvious spin in order to placate the anti-genocide sentiment in this country. If you actually believe this narrative then you are the woefully naive one.
