I’d either run away screaming or I’d throw my hands up and say “I’m not touching this with a ten foot pole, they both suck and everyone except the civilians caught in the crossfire deserve whatever they get.”

To me it seems like the obvious answer, from the perspective of a country that provides significant financial and military support to Israel, is to withdraw that support conditional on Israel giving a defined minimum amount of concern to not committing war crimes and human rights abuses. Things genuinely necessary for defense, fine, the rest, we should not be complicit in.
