While Australia is in that supply chain, “stopping it” wouldn’t do anything.

It would stop Australian workers from being implicated in the genocide of Palestinians.

But all that will happen from this is LM will send the parts to their USA operations and from there, they’ll magically be reassigned to Israel. Or worse: They move production of those parts to another nation and Australians lose their jobs.

Who cares. Albo goes on national TV and says in order to protect Australian workers (and businesses?) from being involved or implicated in genocide these parts will no longer be manufactured here. All Australian workers (and businesses) affected by will be be supported long term by <insert name of special anti-genocide-complicity package here>.

Either way, the parts will still get to Israel. The government holds no actual cards in this equation.

I don’t think you understand how important even the smallest wins on the board are to a people under the threat of extermination.
