Poignant how the election results of a foreign ally can have so much influence on domestic defense policy (or maybe more accurately the politics surrounding that policy). I don't personally know much about domestic defense manufacturing other than whenever someone asks us for something (Canada and JORN, Ukraine and Bushmasters) - a quick glance suggests we're already moving in the direction of domestic missile manufacturing, but I don't know how far along we are there (and thus the relative practicality of saying "let's make more missiles than the current plan"). Makes it hard for a layperson to understand if, in isolation, it's a sensible policy or not ¯\_(ツ)_/¯
It's also really interestingly politically for the Greens to be advocating for lethal weapons manufacturing. Their site only (currently - I assume they'll update it later) has a very hand-wavy general defense "policy" on it, and without having checked I imagine they'll have had a history of advocating against specific defense policies (like AUKUS), but "Greens advocate for increase to domestic lethal weapons manufacturing" was closer to a Chaser headline than an ABC headline in my mind.
