While their statement is a hyperbolic and reductive statement about only the other side of the symbiotic relationship, we must also not strip Israel of its agency. Also, Israel≠Jews, as much as Israel tries to convince you they are the same.

In the macro scale. Yes, Israel is propped up by the west as a powerful tool against other regional powers and the imperial system funnels funds into their upkeep.

But it's also true that in the micro scale. Politicians are more directly and personally rewarded to keep those funds flowing (AIPAC exists regardless of tropes) and Israel uses the leverage they have as one of the more valuable strategic tools to grant them leeway others wouldn't have.

It's a two way street. Israel and The US/west aren't parasites leeching off one or the other, they're symbiotic.
