I've never really understood the protectionist mindset. It kinda only makes sense to me as a fading shadow of WWII paranoia. The invasion of Australia by a foreign adversary has never been something I've worried about (but, maybe, that's _because_ of the alignment with the US). I've also struggled with the practical logistics of it.
