No matter what euphemism is given to our action in the Gulf, we are taking sides. We're taking the side of those who attacked and decapitated a sovereign nation unlawfully. Our actions will result in deaths, directly or indirectly, of many unarmed civilians because we are freeing up US/Israel aircraft to keep carpet bombing Iran. Same as sending F35 parts to Israel to be used on civilian Palestinians.
We are now (unofficially) taking part in the Middle East War which some are already calling the start of WW3. Australian government, you are making this nation a future target without our consent.
