I think you should pay a bit more attention to the original statement that this is always more complicated.
You won't be able to "just stop selling them weapons" or "just sanction them"
There are layered and interlocking reasons why the US inherited the British double dealing on giving Palestine to two different parties at the end of WW-2, and why this hasn't been solved yet, and why the alternate futures for that region all look bad.
