The US sees the existence of Israel as strategically important. The constant flow of weapons and other resources into it is clear evidence of this (if the words of it’s leaders somehow wasn’t).
Before the US it was the UK and for a time even Nazi Germany, albeit before Israel formally existed.
If the US knew that Israel could fill it’s strategic role without further investment it would transfer those resources to another project. That’s ample evidence that Israel requires these resources.
The US didn’t create a state governed and populated by radicals, but they required it.
Fair point. Such a change of course would likely mean less genocide (although the existence of nuclear weapons makes this somewhat less than guaranteed).
That said, a less secure Israel might lose a large chunk of it’s population and industry. Many Israelis have dual citizenships that make leaving fairly easy. Israel as we know it could very well collapse.
