The only way to get Israel to subscribe to our post WWll, “nuanced” version of winning military conflict is to play sugar daddy to them.
Otherwise, they would kick the crap out of many whose crap we would prefer remain internal.
And the rub is, they’d be doing it under a legitimate claim of self-defense.
Furthermore, the private ties between Israel and The United States preclude any kind of psyops campaign to sway American public opinion against Israel in any substantive way.
