You’re not wrong… us Australians can’t really do much. Our government can denounce it, sure, but they’ll probably just follow the US stance as usual. Even then, not much will change. For at least the past 20 years Netanyahu has held the keys. Indirectly, US has plenty of responsibility by enabling them. In other times during the conflict, Israel was more sympathetic and it was instead Jewish or Muslim religious extremists, divided groups or violent Arab/Palestinian resistance that delayed peace efforts
I don’t doubt for a minute that modern-Iran is a threat with Nuclear weapons. Although I’ve always wondered, can a dictatorship really sustain themselves without some perceived or real external threat? To Iran, a US-Israel partnership is a very real threat. Particularly given how ruthless Israel has been in Gaza. As it stands they’ve got the US (with nuclear weapons) and Israel (who refuse to confirm or deny) trying to tell them they can’t even consider having nuclear weapons… that’s not really lending itself to build any sort of trust, which I’d argue is step 1
US currently preaches isolationism, so one choice would’ve been to continue quietly supporting Israel while otherwise staying out of the situation in Gaza/Iran. Another was to public ally denounce it, drop support and otherwise stay out of it. In terms of getting involved, one option was to declare that no further support would be provided. US to apply pressure until Netanyahu ceases and owns up to what they’ve done in Gaza. Support not to return until Israel commits to adhere to a new vision for peace. Final option was to ignore the Gaza situation, continue funding and assist in attacking Iran… Trump and a select few of his team jumped at the latter option. Overall I think it is shortsighted and a shame
